I think 5a is the Seven Stones sound. I remember 5c as the Cirkus sound
although someone who actually owns a MkII would know for sure. I've
played around with the "hammond' organ on the Pinder sample disk and it
sounds like a dead ringer for "Seven Stones". The 6c Church organ is the
sound Pinder used. I hope Markus doesn't die or the world end if I am
mistaken in any of this!
I do have Mike Pinder's original tapes from my #134 which would clear the mystery; HOWEVER, 134 has had bespoke tapes in it since its restoration in 2003-2004, and my memory isn't that good. Brian Kehew's 2nd MkII has standard MkII tapes, so he could readily tell which organ is which, but I don't believe that Brian is on this list.
6C is definitely Pinder's choice.
