I went to see Deep Purple with a friend when I was 16, he was a huge fan, but I went along just to hear Roger Glover.
Before the show we had to find a parking lot or something to consume our sixpacks, being under age. So we strolled away
from the city center, through a posh shopping street where we normally would not go. At the end of the street we saw an elderly man and his wife - and it turned out to be Roger Glover. The funny thing was, Roger had a black pen - and he signed my white t shirt, but my poor friend was all dressed in black. I think he tried to sign the print on his black DP t shirt, but it would not stick to it. Roger probably noticed he was uncomfortable, an signed his hand or something. He was really nice, calm I remember. I probably asked him about his favourite bass, what strings he used etc. I remember trembling with excitement while we drank our beer.
Anyway, the show was not very good, and my friend got angry because I had the autograph on my tee. He never got over it, but I told him that someday I'd buy a Rickenbacker and wipe it's strings with it. I did buy a Rick some years later, and the tee is in it's case.
It's about 20 years since I saw this guy, but I hope he eventually washed his signed hand.......
