Oasis on stage at their homecoming gig at Heaton Park.
About 80,000 fans have turned out for the first of five gigs there.
Support acts Cast and Richard Ashcroft have warmed up the crowds, ready for Oasis to begin their show at about 20:15 GMT.
The Gallagher brothers opened up with Hello, the first number on their smash-hit album What's The Story (Morning Glory)?

The gates have opened and the masses are beginning to pour into Heaton Park.
You have to admire the dedication of all these fans, standing outside in the sweltering heat for many hours in hope of being in pole position for a sweet spot at the gig.
Fans are filing into Heaton Park as the gates are officially open and the build-up to the show is set to really get under way.

In case you haven't heard, several of Manchester's trams have adopted Liam Gallagher's distinctive Mancunian voice as the station announcer.
So I've made it my mission to find one!
However, I've been told by Metrolink staff there are only a handful of these special carriages in circulation - and I'm yet to find one despite spending the afternoon hopping around the city.
The drivers I've spoken to are being very helpful but the trams we've come across so far all have the standard announcer who doesn’t quite have the same Manc twang as Liam.
The search continues.....

But one person might be able to do just that.
Back in 2006, Ben, from Poynton in Cheshire, won a BBC Radio 1 competition to have Noel Gallagher play in his front room - and BBC North West Tonight were there to tell the story.

We've been catching up with the Oasis garden girl - the fan who offered her back yard in Whitefield as a free campsite in exchange for a ticket.
"I've got my campers coming very soon all the way from Newcastle, they've described themselves as Ant and Dec from Wish," Liv Bridge said.
The 30-year-old said she had so many people contact her after she pitched her offer on social media that she was forced to do a whole application process.
"I had a little questionnaire for people to fill out with reasons for coming and how long they'd been a fan," she said.
"There were lots of fake applications, people who didn't have a ticket or just wanted to come for the party."
She said she is still feeling the impact of her viral post on X, which has since been seen by seven million people.
She added: "It was a crazy time and it's still going on, people who I don't even know come up to me and say I've seen you around are you the Oasis garden girl?"

“We’ve only just got the tickets!”
After missing out on securing passes last year, Shay and Wendy decided to take the plunge anyway and flew to Manchester from their home in Dublin this morning.
Their gamble paid off, with Wendy telling us she had only just received confirmation after working with her sister tirelessly on resale websites to get them in time for today.
Shay seemed to be in disbelief at first, and Wendy was physically shaking at the news.
She wasn’t sure exactly how much she’d spent on the tickets, but guessed they could be around £500 each.
But Shay said it was more than worth it, adding Oasis “mean absolutely everything” to him.

Everyone's wondering this - but there actually might not be a clear answer as the band could well decide to mix things up each time they play.
However, while the setlist for Heaton Park has not been confirmed, this was how things lined up when the brothers performed to 70,000 fans in Cardiff.

You might have seen in a sneak peak of the Oasis drone show in our earlier post at 12:02 - but how about getting a better look at how things are shaping up inside Heaton Park?
Well, you're in luck. Oasis have shared this footage of the preparations as the show gets ready to roll.
The countdown is almost over... it's going to be Supersonic.

You won't be looking back in anger if you're at the front of this queue outside Heaton Park.
Crowds are continuing to gather outside the venue ahead of the gates opening at 15:00, with queues snaking seemingly endlessly.
I hope they all packed sunscreen.

Busker Mirai Ito, from Japan, has managed to bag himself a ticket for the last night of Oasis' shows.
The 40-year-old says he “couldn’t give up” on the hope of watching the band after failing to get a pass when they were first released.
So, when he came to Manchester busking in September, he decided to try his luck.
He said most people simply laughed at him but after two weeks a woman offered to sell him her own ticket for face value.
Mirai says he thought it was a scam at first but once she followed through and he received the ticket he cried with joy.
He described it as “a miracle” and says he is filled with appreciation for Manchester, and for Oasis for bringing him here.
Everywhere you look in Manchester today, there's an Oasis reference, from murals on walls to lyrics on windows to flags flying high above Heaton Park's walkways.
It's fair to say the city is warmly welcoming back two of its most famous sons.

Dylan Matthews, 28, from Birkenhead, said he discovered the band through his parents.
“My mum and dad were Oasis superfans," he said.
"They took me to watch the band when I was 11 and It means a lot to be here," he said.
April Lipscomb, 33, has travelled from London.
"It’s been my dream to be here. I was too young in the 90s and I thought I missed my chance," she said.
"The atmosphere is great already. It so great to be here with all the Mancs."

Hundreds of fans are braving the heat in the queue for the official Oasis merchandise stand at St Peter’s Square in the city centre.
I’ve heard from staff that it’s at least a 45-minute wait.
Fans had better have brought their wallets and purses, however, with bucket hats priced at £35 and some hoodies an eye-watering £90.
Though I don’t think anyone will be shouting ‘HOW MUCH?’ on a day as momentous as today.
The gates to Heaton Park are set to open at 15:00 BST, but organisers have advised ticket-holders to plan ahead and arrive early to allow time to get through the crowds.
Support acts Cast and Richard Ashcroft will then take to the stage before Oasis, with curfew at 22:30 BST.

Oasis - 20:15
Curfew - 22:30
Oasis fan Glen Clancy missed out on the hottest tickets in town but is consoling himself with making his own entertainment.

Bags have to be smaller than A4 size so I bought one of those moon bags everybody got a few summers back.
Sun cream. Prescription sun glasses. Watch. Phone. 500ml bottle of aqua - with refills available onsite of course.
Took my headphones for listening to the Mad For Oasis series on the tram there (shameless plug there, sorry).
I also opted for a boonie hat over the more traditional bucket hat as it proved invaluable when I walked up the scorching Portugal coast for two weeks last summer.
And its gonna be very very hot!

About 340,000 Oasis fans were lucky enough to secure tickets for their five homecoming shows in Manchester.
But how many of them were in the huge crowd in 1996 when the Gallagher brothers took to the stage only a few miles away, at their beloved Manchester City's former Maine Road stadium?
It was just a stone's throw from their childhood home in Burnage.
Here are Liam and Noel popping in - separately, of course - for a brew with their mum.
Since they burst into the public eye more than three decades ago, Oasis have been central to their fans' lives.
From love stories to heartache, from teenage high-jinx to family drama, from being young, free and reckless to getting older and facing life's challenges, the music made by Liam and Noel Gallagher has been the soundtrack of many lives.
Ahead of the band's reunion shows, some of those fans have shared the stories of how Oasis have impacted their lives with an exclusive series presented by Noel's daughter Anaïs Gallagher for BBC Sounds.
Anaïs Gallagher explores stories of the fans whose lives have been changed by Oasis.
