Champions Forever, Ali, Frazier , Foreman, Norton

Hello please can anybody tell me where I can find the soundtrack music from this splendid boxing movie.
There is a classical piece at the opening of the video which I like, but there is also a song with the lyrics "Champions Forever" that is played throughout the documentry.
If anyone can help , it would be greatly appreciated, thanks.

Oh, I have heard that a composer/artist named Bebu Silvetti did some work for this video, but cannot find the songs anywhere.
