And just to complete my exciting question.
The fairground organ is heard at the beginning of 'Voice of Necam' straight after 'Please don't touch'.
Good question by the way.
Er, I think not. The Santa Monica recordings are at the transition between Narnia and Carry On...., the organ is credited as "The Robert Morton Pipe Organ", which implies there has only been one, there have been several, apparently. As the album notes state, it was destroyed weeks later in a studio fire, which also destroyed the early recordings of "Octave" by the Moody Blues who were using the studio at the time. They decamped to Mike Pinder's studio in Malibu as a result.
Sampling wasn't available in 1977 when the album was made. The Santa Monica fairground features in the album inner-sleeve photos, and the recording are of automata, eg/ the "Bimbo the Clown" and other associated bits
