Welcome to the Mudcat, Cres! I love this song, too, and, now, listening to the midi of it, I realise I didn't get it quite right. Will have to correct it sometime, soon!
I can't find one recording of it on google. After next Tuesday, the fellah who could probably answer your question, Dick Greenhaus, ought to be back at his company, Camsco Records . If you give him a call, I am sure he could help you. If you join the MUdcat (it's free and painless) you could send him a PM (private message) on your Personal Page and get an answer that way.
