Incidental Music / Soundtrack
I just watched my old self-recorded VHS tape of this (with all the original music) and there are 16 other pieces of incidental music (harmonica, organ, piano, Sunshine's flute, etc.) in between scenes, no doubt composed by either Charles Fox or Joseph Turrin, the composer and orchestrator for the film. Unfortunately, they'll probably never release those, however, I WAS able to find the main six songs free online at www.limewire.com - so go there and burn your own soundtrack.
There's also one famous classical piece that Counselor Gary Calahan is listening to in his cabin when Ferris visits him. Anyone recall which piece it is? It's very familiar but the name and composer escapes me.
Thanks!
