Thousands of green-shirted NI fans have belted out a rousing rendition of their adopted theme song – Neil Diamond’s Sweet Caroline.
The atmosphere is really building here.
A song which has haunted me for 30 years...

Jonny and Corry Evans could go into the history books as the first brothers to play at a major tournament for Northern Ireland.
So BBC Sport couldn't resist getting in touch with their proud parents to ask for some embarrassing photos of the pair when they were younger.
Altogether now...Aaaaaaaaaaah.

Image source, Press EyeChris Brunt may have been ruled out of playing at Euro 2016 because of a bad knee injury – but he hasn’t been forgotten by his Northern Ireland team-mates.
On Saturday, the West Brom man trained with Michael O’Neill’s men on the eve of their first ever appearance at the European Championship finals.
And today, 31-year-old Brunt was in his NI tracksuit and on the police-escorted team bus travelling from the hotel on the Promenade des Anglais.
On getting to the impressive 35,000-capacity Stade de Nice, he made a quick change into his best civvies as he's on media duty for today’s BBC TV coverage.

"A bit of surprise by Michael O'Neill, playing four defenders in what looks like being a 4-5-1 set-up. Fleetwood Town's Conor McLaughlin plays with Premier League trio Craig Cathcart, Gareth McAuley and Jonny Evans."

...the bench. But you can bet you'll hear his song at some point this afternoon.
Sung to the tune of 90s dance classic Freed from Desire by Gala, Wigan fan Sean Kennedy rewrote the lyrics and renamed the tune 'Will Grigg's on fire' - in honour of the Latics and Northern Ireland striker.
It's been sung on the terraces in the England for the last few weeks and it was even played at half-time in the Wales game on Saturday.
Here's Grigg's team-mates, external giving it a go (bar Roy Carroll who wasn't having any of it)

Former Northern Ireland captain in Nice
"The most important news is that Kyle Lafferty is fit and ready to start.
"All the names that have banded about to play with Lafferty, none are on the starting list.
"It will be interesting to see who supports Kyle Lafferty"
Poland v Northern Ireland (17:00 BST)
So striker Kyle Lafferty has overcome the niggling groin problems he suffered in training earlier this week to take his place in the starting XI.
Looks like Steve Davis will play just behind him.
Northern Ireland: McGovern, McLaughlin, Cathcart, McAuley, J Evans, Ferguson, Baird, Norwood, McNair, Davis, Lafferty.

Located to the west of Nice, three miles from the city's airport, the 36,000-capacity Stade de Nice is a multi-event arena designed to host rugby, tennis, motorsport and concerts as well as football. Opened in 2013, the stadium also hosts France's national museum of sport.
Usually known as the Allianz Riviera for sponsorship reasons, during Euro 2016 it will instead simply be the Stade de Nice.
Kind of looks like a big greenhouse to me...

"It is virtually three cup finals in three games for Northern Ireland so they are going to give everything.
"They are very, very, good at stopping the opposition playing."

Image source, Press Eye"Northern Ireland’s football team have been absolutely flying lately, so apt perhaps for an airport to be getting in on the act.
"The George Best Belfast City Airport has been renamed for today in honour of striker Kyle Lafferty who scored seven goals in the qualifying campaign.
"Sure George wouldn’t have minded, his name will be back above the door again on Monday."
