Multi-instrumentalist Chris Stainton has been a major presence on the British music scene since joining Joe Cocker's backing group, the Grease Band, in 1966. Although he wasn't a part of the classic lineup of the free-standing version of that group, his longtime association with Cocker during the latter's prime years made him very much in demand as a player, mostly on keyboards but also on the bass. He was born Christopher Stainton in Sheffield, South Yorkshire, England in 1944, and attended Rowlinson Technical School in Sheffield. He began playing bass in the late '50s, initially with a group called Johnny Tempest & the Mariners, who later evolved into the Cadillacs. After that apprenticeship, he chanced to cross paths with a childhood friend, John Robert Cocker, who was by then pursuing a career in rock & roll as Joe Cocker, and in need of a new backing group. Stainton became the anchor of that band, contributing as a songwriter in tandem with Cocker as well as playing the bass. The group went through several transitions between 1966 and 1969, in the process evolving from a jazz-oriented sound to more of a hard R&B sound, and Stainton relinquished the bassist spot to Alan Spenner (late of Wynder K. Frog) and switched to keyboards. The resulting "classic" version of Joe Cocker's Grease Band impressed critics and audiences nearly as much as the singer did, and Stainton was part of the lineup that toured the U.S. in 1969 and played a renowned set at Woodstock that August, which has since been released in its entirety.
