Would anyone know where I can find say Ellingtons arrangments for his band? Or pretty much any sheet music for a big band. It would be nice if it was a free (and hopefully legal) download.

I've already got 2 fake books, but I really wanted to see how jazz bands use voice leading and what each sax or trumpet does in each song.

I don't know where you could get full band arrangements for free, but how about finding decent midis of the whole band playing together, then importing it into software which will then show you the notes?
