Stairway to Heaven (1971). Jimmy Page and Robert Plant /when worlds collide/

Critic Steve Simels apparently didn't get along with Frank Zappa. He goes on to post a link to the Zappa version of Stairway to Heaven, as evidence. Ok, it's not exactly a link. It's an embedded player via an MP3 search engine. Let me give it a try:

Note that the original guitar solo is played by the horn section in this version, which is surprisingly cool.

By the way, last night Marin Alsop programmed music by Zappa as well as Philip Glass take on David Bowie's Heroes.
