Kudos to National Nitwit for uncovering the sad story of British musician and sometime member of the Rolling Stones Trevor Whittaker, who died today of pneumonia. The unofficial "Eighth Stone" was 64.
From the obituary:
Whittaker was active in the London rhythm and blues music scene that spwaned the Stones and many other sixties rock acts. A multi-instrumentalist, Whittaker occasionally filled in for members on tour, and performed on a number of Stones recordings.
