Whats the name of the song???

[mvmike]

There was a song in the 60/70's ( Rock and Roll ) that ended with orchestral music and a low toned male voice reading text that sounded as if you were in a theater watching the end of am epic movie. The whole thing ended with a loud chinese Gong sound. Can anyone remember the song name and band? For some reason I thought it was a Zepplin song. - Thanks, Mike
