The Gers faithful created one hell of a din throughout the semi-final second leg and when the full-time whistle went, the stadium erupted.
A 3-2 aggregate win over Bundesliga side RB Leipzing put them into the final in Seville and the supporters made sure their emotion was felt.
Our very own Ally McCoist was watching on in awe - and may well have partied long into the night with Alan Brazil struggling to reach him on the talkSPORT Breakfast.
He told BT SPORT: "I can't tell you how proud I am of that team.
"I've been fortunate enough to come to this place and I've seen victories over Bayern Munich, I've seen victories over Dynamo Kiev, I've seen victories over Leeds United but tonight's atmosphere has been the best - the best!"
He's not wrong!
One video from the night showed the BT gantry bobbing up and down dramatically as supporters made sure the likes of James Tavernier, Glen Kamara, and John Lundstrum, the goalscorers on the night, felt their presence.
talkSPORT host Adrian Durham was also there and confirmed the stadium was, most definitely, rocking.
He told Brazil: "It was absolutely extraordinary. I've been watching football for 50 years and I haven't witnessed an atmosphere like that. I've been to big games all across the world.
"The big stand was literally shaking. I'm not even joking. It's a cliche but it was absolutely true. It was shaking. It was absolutely stunning."
"Ibrox baby, it's just different," tweeted Ianis Hagi after the match - and he's right.
But while supporters on the light blue side of Glasgow partied the night away, one rang into the Sports Bar.
He'd taken a look in his cupboard and found Jamie O'Hara's recipts - and he wasn't about to let him forget about them.
"Jamie, I've got one question for you," Steve said wryly. "About, maybe, a year ago, you slated Rangers on the radio and you said the Bournemouth job was bigger than the Rangers job.
"I did," confirmed the ex-Tottenham midfielder.
The fan continued: "I hope you have got egg on your face tonight, son, because you have. Fair play, you're bigging up the Rangers [now] but how silly do you feel?"
"Not really. You're changing my mind, I kind of want Frankfurt to win now," joked O'Hara after the call out.
"I took some stick for it, lads. We all make mistakes. I said it was a bigger job, I meant better, we addressed that over a year ago.
"Well done tonight. You deserve everything you got. It was was an unbelievable performance to get there."
But O'Hara did have one last thing to say.
Queried if he still felt the same way, he replied: "Yes - because Bournemouth are in the Premier Legaue now."
He'd better hope Ally doesn't find him…
