My first PG gig was, as I've tediously droned on about elsewhere, when I chatted with Phil Collins and frightened Robert Fripp.
Tue 11 March 1980, London Hammersmith Odeon, rear stalls. Having watched support act Random Hold (David Rhodes's band of the time) my brother, a friend and I were chatting, and leaned back to let a man and woman get past us to their seats on my right. My companions were suddenly then excitedly pointing and I realised the couple were Phil Collins and (we assumed) his girlfriend. By this point others had recognised him and were talking to him and getting him to sign their PG programmes, which were a mocked-up Mao 'little red book' with "Tour of China 1984" on the cover. Oh, that PG, he kerrrr-aaaazy.
We had a stack of 10 of these for ourselves and various friends & family. As I was next to PC I was given the task of asking him to sign them all. My nervous 14yo self querolously asked if he'd mind making 10 Genesis fans very happy. He looked at the stack of programmes, looked at me and said "What, do you run a fucking library or something?!" Then he laughed and said "C'mon, give 'em 'ere" and diligently signed them all, pausing to flick through and read one (I never knew who ended up getting that sanctified copy and didn't think to make sure it was me). He asked me what I thought of Random Hold, then we talked about what was playing over the PA which he told me was Larry Fast, then keyboardist in PG's band.
Shortly after, I saw Robert Fripp talking to someone in the aisle. Not believing my luck that I'd get autographs from and chat with two of my music heroes - for I naively assumed RF would be just as amenable as PC - I went up to him and brightly said "Hello, you're Robert Fripp aren't you?" at which he gasped, looked really scared, went "NO!" then turned and literally ran to the exit - his legs a blur like the Isle of Man symbol spinning in a high wind.
Oh and by the way I loved the gig.
