Amazing crude 1977 bootleg material from THE CRAMPS, from the very first bootleg 45 I ever purchased back in high school. The A-side is the band’s ridiculous take on the Red Crayola’s “Hurricane Fighter Plane”, and the b-side is this outstanding near-instrumental that later showed up on their first album.
Note the very polite, likely bewildered clapping after the song ends. Back of the single says “critics threw up”.
