 Oldfield went on to play on Ayers's albums "Shooting at the Moon" (1970) and "Whatevershebringswesing" (1971), and played mandolin on "Edgar Broughton Band" (1971).All three albums were recorded at Abbey Road Studios, where Oldfield familiarised himself with a variety of instruments, such as orchestral percussion, piano, Mellotron, and harpsichord, and started to write and put down musical ideas of his own.While doing so Oldfield took up work as a reserve guitarist in a stage production of "Hair" at the Shaftesbury Theatre, where he played and gigged with Alex Harvey.
