Schlong Weasel was a concept band that had rotating
membership and one (or less) structured song per show, during which they
destroyed their instruments.
Houston-based, there were so many different bands under this name at one point that they had a 6-band "Schlong-off" to decide the title ownership.
Many ex-Weasels are found in more respectable Texas bands these days: The Party Owls, Linus Pauling Quartet, and Charlambides, to name a few.
