Talking about the Crew, you can’t discount the remarkable and bizarre story of Jim Gordon. In addition to doing thousands of sessions, also played with Traffic, Derek and the Dominoes, Zappa, Delaney and Bonnie, Alice Cooper, Plastic Ono, etc. Geez, he even co-authored (arguably) the coda to Layla. Amazingly versatile and distinctive drummer. Undone apparently by his then undiagnosed schizophrenia, and murder of his mother (for which he now serves a life sentence at Vacaville).
Other “character” drummers I dig are the inimitable Bernard Purdie, and yes Charlie Watts whose meanderings around the beat with Keef have always been an integral part of the Stones sound. Feel better Charlie!!
