Actually, to counter Psuedo_Intellectual's write up, The album was NOT originally produced in 1972. It was recreated in 1972. The original was produced in 1970, is widely accepted as the best recording of the album, and was lacking the tracks Could We Start Again Please and Then we are decided.

The Original Cast was:
