Track times are present on the sleeve artwork, which indicate the EP is a 45. However, this was later contradicted by Beavhead's appearance on the compilation CD, SO*_WHATtypeofMUSICDOYOUMAKE* at 33rpm and a 6:53 track time.
It's unclear whether the artwork on this EP was produced with the wrong track times, or the CD erroneously included Beavhead at the wrong speed.
Given the cheeky note from the sleeve artist found on the subsequent EP, Customer Service -- "None of the times on these tracks are correct. I did ask them for the details but they never got back to me so I made them up. Sorry, if you want to complain please do so, see how far you get." -- the former seems more likely.
EDIT 2024: And now here we are more than 20 years later, and Yunx's revival on Bandcamp confirms the 33rpm speed.
