I disagree. I think its absolutely boss when we do that.
It's been starting earlier and has been carried on at least until the teams walk out. But it's also had a certain defiance about it. Either drowning out the mancs, showing Dortmund how it's done but most importantly for the 96 as always, but especially the last couple of games. Slower would be better (although at least everyone's at the same pace) but at whatever speed I'll personally never tire of hearing it repeatedly like has been happening.
On a different note, I was in the main stand for the first time since Klopp's been here, low down and central, and it was fascinating to see his interraction with the crowd at close quarters. At one point he seemed to be asking for a bit of calm or patience or something. Then next minute he's nodding in appreciation of, or in agreement with, the applause a passage of play has received. He's basically a supporter along with the rest of us, challenging for every ball, fully engaged. It reminded me of that Shanks interview where he says he convinced he's headed a few balls that were going in the net, kept them out.
As for him conducting the cheers at the end. Everyone was just cheering and laughing with pure, simple pleasure and it was boss! Two finals in his first season? Definitely making the people happy.
