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, he showed a flair for publicity and projected the Stones as the group parents loved to hate.
He later became sole manager of the group and is credited with the production of their earlier records.
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.
