"A Fool Am I"
This disc was auctioned by Cooper-Owen in November 2004. It was advertised as a John Lennon demo. Indeed, it sounds like a demo and indeed, it sounds like Lennon but it doesn't take too close of a listen to realize that it's not John Lennon.
The auction provoked some discussion on Yahoo's Beatleg Group. That discussion can be read below. Thanks to the research of "jason1014", it has been determined that this is the same track that is found on the vintage vinyl bootleg titled Goodnight Vienna.
