Does it ever confuse you when you can't quite work out who is the lead singer in an act? Jump the Gun is a good example. The tune was sung by a couple of the band, so at least they shared the work.
In 1992, our friends in the Netherlands sent today's birthday boy Humphrey Campbell. But if you watch the video, there's three of him (and briefly a fourth). Or perhaps only one of the is Humph, and they don't know which one of them it is. I had trouble working it out. Did you? (the song starts at 1.31)
Humphrey is 60 today.
