As we head into the evening, here is a reminder of which acts are due on the main stage:
Nadira Tudor
Reporting from Hylands Park
Eddie Bodsworth, 58, has travelled over from Fairford, Gloucestershire.
He mainly came to see Stereophonics perform earlier.
"[It's] my first Radio 2 in the Park and my first time in Essex," he says. "I think it’s a stunning place and setting."
We could not agree more, Eddie.

BBC Essex's Matt Mackay was just nipping to the loo when he was approached by a man looking for directions.
That man was no other than tonight's headliner Bryan Adams.
This is not how we expected to tell you Bryan Adams has arrived in Chelmsford, but... Bryan Adams has arrived in Chelmsford.
If you're not in Chelmsford today, one thing you should know is Jessie J knows how to interact with a crowd.
She speaks so openly to her audience, getting them laughing, cheering and singing along.
The audience is nothing short of captivated by the singer, even more so when she brings her young son on stage to sing his own rendition of Happy Birthday along with the crowd.
A chorus of "awwws" ripple across the audience. So cute.
Jessie J tells the crowd of her breast cancer surgery 11 weeks ago.
"The last show I did, I had no idea what was going to happen," she says.
"I'm still very much in the recovery process. I'm definitely not ready for back bends. Well, I am, but my doctors are like: 'Calm down girl.'
"I'm so grateful to be here... I'm so grateful to see so many of you singing along after all these years.
"It truly feels like I'm a little kid still doing what I love."

Married couple Tony and Tracy Percibal have travelled down from Norfolk.
The pair were childhood best friends and tied the knot two years ago.
“We are making memories," says Tracy.
There is a lovely feeling at the start of Jessie J's set as she opens with an acoustic version of her song Domino.
She asks the crowd: "Are you ready to have some fun?"
The crowd is singing along with her as she performs in a stunning and glittery silver outfit.
The Chelmsford crowd cheer as Dame Elaine Paige welcomes Jessie J on the main stage.
Jessie, 37, is a Brit Award winner and has sold more than 20 million records with global hits including Price Tag, Domino and Bang Bang.
The Essex singer revealed her early breast cancer diagnosis at the beginning of June and received widespread support from fellow colleagues for sharing her experience.

Reporting from Hylands Park
Glyn Boallman and Gary Abraham are among a group of eight friends who have come from Teignmouth in Devon.
All eight are wearing matching outfits.
Mr Boallman admitted they wore the same shirts to Radio 2 in the Park in Preston last year: "Nobody gets lost, you see!"
Ahead of her set at 17:00 BST, Jessie J said this felt like a homecoming gig.
"All my family are out there, some childhood friends," she said.
"As we got closer and we went through Romford, where I grew up - I was born in Seven Kings - this is my ends."
She added she had fond memories of when she performed at Hylands Park during V Festival on numerous occasions.
"When you're born and raised in Essex, that is something that stays in your blood.
"It never leaves, I can feel my accent getting stronger as the day goes on."
It's fair to say we've had some horrible weather this past week, so festival-goers might be wondering how the rest of the day’s looking.
Well, it's good news.
It's still looking warm and clear, and temperatures should only drop to about 18C this evening towards the end of the performances.
Be sure to stay hydrated in between your singing and dancing!
The crowd seemed to love the party vibes from Kid Creole & The Coconuts.
The band's trumpet symphonies were spreading waves of positivity across Hylands Park.
"Thank you, music lovers," Kid Creole shouted as he did the conga on stage - legendary moves.

Kid Creole & The Coconuts have been rocking the stage.
The group scored seven UK Top 40 hits in the 1980s, including three Top 10 singles – Annie, I'm Not Your Daddy, It's a Wonderful Thing Baby and Stool Pigeon.
Kid Creole said he was "looking forward" to bringing "three stunning Coconuts and the baddest band in the land" to Hylands Park.
Ronan Keating is in Chelmsford. I repeat, Ronan Keating is in Chelmsford.
You can watch him perform from 18:00 BST.
Not at the festival today or did you miss Ella Henderson earlier?
Worry not. Let us just take a moment again for the singer, who looked incredible on stage this afternoon.
The crowd adored her set and she really helped to keep the party atmosphere going after Stereophonics.

Reporting from Hylands Park
Larry Eliemenye, 40, lives locally and has come to Hylands Park with his family.
Unfortunately, due to traffic in the area, he missed Stereophonics' set earlier, but he says he cannot wait for Jessie J at 17:00 BST.
Not long left to wait, Larry! Up next, though, is Kid Creole & The Coconuts.
Essex's very own Rylan Clark looked glorious on stage earlier while he was introducing Ella Henderson.
Just look at that neat hair, perfectly trimmed beard and crisp shirt.
Hopefully we see some more of him later.
Marti Pellow has finished his set and is now talking with Radio 2's Jo Whiley and Romesh Ranganathan backstage.
"With an audience like that, I could work with that all day," he tells them.
"It was a pleasure to hang out with the good folks of Chelmsford."
"You have been a pleasure to sing for this afternoon," he tells the Chelmsford crowd.
"This is fantastic - what a great day. I love Essex."
The feeling's mutual, Marti!
Adam May, 27, from Chelmsford is at the festival with his partner Abbey Kitchenham, 26, and he just might be Essex's biggest Stereophonics fan.
Today's set by the band was his 21st time seeing them and his eighth time this year alone.
He even went to San Francisco in the United States to see them earlier this year. What an effort!
"Stereophonics were a brilliant start to the Chelmsford party with Dakota and Maybe Tomorrow getting everyone to sing along," says Adam.
"I'm also looking forward to Bryan Adams headlining later."
