Check 0:05-0:18. I can't believe I posted a Left Rights song and then watched your video right after and found it was sampled in another Left Rights song.
Klaatu's debut album 3:47 EST was mainly known as the album that everyone thought might have been secretly recorded by the Beatles for a few weeks in 1977 only to be revealed to be from a band from Toronto.
The album is mostly progressive rock but there's this one weird song, "Sir Bodsworth Rugglesby III" that sounds like it could have been performed by the Muppets with Jim Henson as Rowlf (or as Dr. Teeth, I suppose) doing a fake British accent.
