I was curious to know what was the first commercial cassette single (aka cass-single) in the US and the UK? I seem to recall a radio program stating in the US, it was the Go-Gos and their song "Vacation." I realize this would have been a rare thing back then. Does anybody have any ideas?

Hmm..good question. I am guessing it has to be the early 80's. Other then that, no idea.:confused:
