Inspired by a previous post regarding the Fab Four, and being a Stones fan for many years, yes I'm old .
in his book Stone Alone, Bill Wyman has numerous references to Keef and Mick. In a big book about the Stones ( can't remember the title, nor find it at the moment) it sounds as if there were 3 members of the Rolling Stones, Mick, Keef and Charlie.
im open for education, from the more enlightened members here.
