In 1963 he founded the theatrical agency Scala Brown Associates with Sir William Pigott-Brown.
The agency was known for representing actors, directors and musicians, including Richard Harris, Cat Stevens, Ben Carruthers and Jim Browne.
Although not a film producer, in 1965 Scala bought the rights to the comic strip character Modesty Blaise with the intention of casting Barbara Steele as the eponymous heroine in a feature-length production, before ultimately selling the rights to produce the film to Joseph Janni (who brought in the fashionable Italian actress Monica Vitti to play Modesty instead).
In the late 1960s Scala took off to live in Spanish Sahara, Spain, Sri Lanka, and Switzerland, painting and recording ethnic music, including that of the Dervish Ganoua sect from Tangiers.
Scala produced the first direct-to-disc album for the band Warsaw Pakt, before founding ESP Music and Management, an agency which represented record producers Chris Kimsey (The Rolling Stones), Stuart Levine (Simply Red) and B.B.
