I was one of the first 50 people to join the Stones' UK fan club in 1964, for 2/6d, and it got me a signed picture. Years later (I kept up my membership) it got me an invitation to the taping of Rock 'n' Roll Circus, but I couldn't go because they said it would end late and it was the night before I had a big exam.
Looking back, my favorite periods were those early blues years, and then the Mick Taylor years. For me they went off the boil after that, but I'll always love them.
