This is one of the better things I found this weekend. The band is the Tater Totz. I used to play them on my radio show in college, although I've forgotten about them until coming upon this clip. From what I remember, they were basically a noise rock band who did a lot of covers of 1960s rock, including a lot of Beatles. For their appearance at a Beatlefest convention in the late 1980s, they figured the Plastic Ono Band was fair game for a tribute battle of the bands. I applaud them loudly for doing so.
