 After ten performances Oldfield grew bored of the job and was fired after he decided to play his part for "Let the Sunshine In" in 7/8 time.By mid-1971, Oldfield had assembled a demo tape containing sections of a longform instrumental that became "Tubular Bells (Part One)", initially entitled "Opus One".After attempts to persuade record labels to take on the project came to nothing, in September 1971 Oldfield, now a session musician and bass guitarist for the Arthur Louis Band, attended recording sessions at The Manor Studio near Kidlington, Oxfordshire, owned by businessman Richard Branson and run by engineers Tom Newman and Simon Heyworth.
