Very completely awesome pic, pc31. I can almost hear Ringo saying "Hang on Pete, I'll be done soon!". December 26, 1961? Tower Ballroom, right?
I think I see The Hurricane's lead guitarist (smiling looking in the camera' direction behind the MC)? Paul clearly is working on some bass line just before going on stage. The guy at the far bottom right looks a little bit like Stu, but I don't guess he would have been there at the time? And is that Dot Rhone in the bottom left?
I notice that even though The Beatles are topping the bill, their name is spelt wrong on the bill on the wall "The Beetles".
