This is a group called Red Box. The song is "Thge Circle and the Square," from the 1987 12" EP Heart of the Sun - an excellent recording, I might add.
Admin note: I'm tired of moderating the continuous spam being posted here. Deleting 10-20 offensive, pornographic or otherwise unrelated comments every day is not what I am here for. Because you guys can't police yourselves and behave, for now I've disabled the commenting functionality altogether. We'll see if we can come up with a better system in future.
