Oldham was a publicist for The Beatles before working for agent Eric Easton, with whom he became joint manager of The Rolling Stones in April 1963.
Modelling himself closely on Phil Spector, the sharply-dressed svengali showed a flair for publicity and projected the Stones as the group parents loved to hate with inspired media feeds like: “Would you let your daughter marry a Rolling Stone?”
He later became the sole manager of the group and is credited with producing their earlier records. He was also responsible for discovering Marianne Faithfull and Vashti Bunyan.
He stopped working with the group in 1967 after setting up his own record company, Immediate, which recorded The Nice, The Small Faces and Chris Farlowe.
Immediate encapsulated Carnaby Street and Swinging London in the very grooves of its releases, but sadly ended in financial and organisation disaster. Immediate went bankrupt in 1970.
