if anyone is interested...is Brian Jones. he founded the band, was the bluesman and the best all round musician (he played many insturments--Sitar on Paint it Black/Marimba on Under my Thumb as well as being the first British musician to play bottleneck slide guitar on a record). He was forced into the back ground by mick and keith and their manager Andrew loog oldham and driven to becoming one of the first rock and roll casualties (he was the first stone to becoming an alcoholic junkie--he outdid Keith richards in excess for a while). In 1969 he went swimming while drunk and drowned. To this day, some people think he was murdered and there is a movie coming out saying Jones was murdered called "Stoned".
It should also be noted that the 60s stones rocked...the first post-brian record they had was "Honky Tonk Woman"---a crappy record, and the begginning of the end of the stones as a great band.
