ANARCHY!!!!!!
You may not of heard about this one, but there was a short piece called "Anarchy," which was basically a send-up for punk metal, where all the members would yell "ANARCHY!" It was a more humorous piece than a song, but it was fairly recognized in the 80's, even though it was only played eight times. If I can spell the number, then you should know that it is a rare piece.
First played on March 4, 1985, the piece has no history past 1988. It was first played at Hunt's, in Burlington, Vermont.
You better get a good collection of rare concerts, for this song is in no albums, only bootlegs. Sorry, my phans.
