actually, i didn't know they reochestrated those bits of music.
Anyway, I believe the new loop was made to place in DLP. Now i know that a lot of the music for DLP has been re arranged by John Debney (Phantom Manor, It's a Small World, Tea Cups, Alice Labyrinth...). So *maybe* he did this too. a total wild guess though, and probably totally wrong too, as i imagine they'd just ask a cheaper rag time conducter to do that. but maybe it will help you in your search.... a little.
