Years ago I used to hang around outside the Wolverhampton Civic Hall collecting autographs. When Alice Cooper played there, I had to go and try to meet him and get his autograph. I turned up, and a bunch of the usual autograph collecting faces were there. Normally we'd hang out a bit, then the band would turn up. The band would then hang out with us on the street for a while generally chatting, signing autographs and taking selfies, before heading into the venue for that night's gig.
Only when Alice Cooper turned up, his double decker tour bus immediately parked itself right across the pavement where we were standing, then for a long time did nothing. Eventually someone came off the bus, and one of us asked about autographs. They looked annoyed, and went back on the bus. Eventually they came back out, and shouted instructions at us that we must give him one item each for signing. These items would then be taken onto the bus to be signed by Alice. If anyone tried to give more than one item for signing, or made any requests for what to be signed, or complained in any way, then all of our items collectively would be thrown in the bin and that would be that. We each gave in our item, and after a while they were handed back out to us from the bus with an illegible scrawled line sharpie'd across it.
After a short interlude, we were informed to stand back as Alice would now be escorted off the bus, and any interference with that would be met with the police being called. At this point we started openly laughing at the situation, as we were a bunch of friendly black country folk who had nothing but respect for the man. So we duly all stood back, and he was rushed out of the bus and into the venue under a blanket, escorted by two security guards. Accompanied, I must confess, by various black country accented shouts of 'fucking wanker', 'I didn't realise you were a dick' and 'you've done nothing since the 80's'.
I've never before or since seen an artist completely lose the crowd before they even stepped on stage. Apparently word of that evening's events spread at the gig that night. He received some stick.
