I'm going through all this vinyl and I've just pulled two 12"s out of the same Butthole Surfers Piouhgd jacket. One is the LP you'd expect, the other is a white label (no writing) single. One track only on one side and two on the other. It's definitely Butthole Surfers. We've played it at 33 and 45 but can't tell which is right as, well, it's the Surfers. Can you help? There's no lyrics in particular it just goes ugher-ugher-ugher over and over to a rolling drone... Do you know what it might be?
