The atmosphere before, during and after Celtic's emphatic 3-0 win against Rangers was up there with one of the best in recent memory.
In fact, ahead of the grudge Scottish Premiership clash on Wednesday night, a rendition of 'You'll Never Walk Alone' rang around Celtic Park on a special evening for the famous green and white.
Check out this fan footage from the stands. Is this the best atmosphere in world football?
Celtic got off to the perfect start when Reo Hatate, a new signing from Japanese side Kawasaki Frontale, netted with just five minutes on the clock.
After picking up the Man of the Match award on his debut against Hibernian - and scoring a screamer against Hearts last week - the £1.4 million man has already become a fan favourite after last night's heroics.
I mean, just check out the limbs after Hatate opened the scoring.
That goal only helped the atmosphere grow inside Celtic Park, with this YouTube compilation of the scenes inside the famous stadium showing how incredible it really was.
You can watch it below.
Hatate then notched his second goal of the game, just three minutes before the half-time whistle, before Liel Abada made it 3-0 in the 44th minute.
Oh, did i mention Hatate scored another screamer to make it two?
After the full-time whistle, Celtic midfielder Matt O'Riley, who joined the club from MK Dons in January, couldn't quite believe the atmosphere during last night's Old Firm.
“We’ve got the best fans in the world, honestly. I’ve never seen anything like that in my life," he told Sky Sports.
"The atmosphere was electric tonight, as is every derby. Tonight, the fans were awarded with a top-class performance that puts Celtic at the top of the table.
"There is still a long way to go in the season, but fans are confident. It was a great display against that season’s champions.
"If performances stay like they are just now, and improve into the second half, Celtic can push for the league and bring it back home."
