Annie Lennox sings a song entitled "Into the West" over the final credits (well worth watching for the fine watercolor   drawings).

It seemed to me there was a great deal more music (diagetic, in other words, occuringon screen as performed by characters)in the third film than in the previous two; and very fine music it was.   The scene where Pippin (Billy Boyd)sings a song he apparently wrote himself (the tune anyway, I heard) is simply stunning and I think it's an emotional centerpiece of the film...
