Bill Wyman leaves (1992)
After 30 years of playing bass without appearing to move a muscle, Bill Wyman became, in 1992, the second Stone to leave the band of his own volition.
By far the most interesting consequence of this was his tell-all autobiography, Stone Alone, in which he claims that Jagger and Richards were "not the sort of blokes I'd have chosen as mates if I hadn't joined them in a group" and that they monopolised both songwriting credits and the limelight.
Wyman, however, was happy to point out that he'd slept with more groupies than all the others put together. Nice.
