Richard Hartley
From RockyWiki
Richard Hartley was part of the original 4-piece band that played nightly in the The Rocky Horror Show in London. Hartley met Richard O'Brien via Jim Sharman, and began working with him before the debut of Rocky Horror as a play. Hartley served as the arranger for the original music for the show.
A long professional relationship developed between Hartley and O'Brien, that included not only The Rocky Horror Picture Show and its follow-up film, Shock Treatment, but also O'Brien's other stage creations Tee Zee and Disaster. Together they also worked on the yet-to-be produced Revenge Of The Old Queen.
