LesPaul43, they're actually called Black Uhuru. Uhura was on Star Trek.
They are awesome, though. Other good songs of theirs are:
I Love King Selassie
Party Next Door
Guess Who's Coming to Dinner
Solidarity
And if you like them, you might want to check out Michael Rose's solo stuff. He was their singer, and has done some pretty decent work--even sometimes with a bit of a dancehall or R & B flavor to it.
