I need to know the group that did a late 80's song that went..."I need you...sha na na na na, you're what I want....oh girl...i want you....you're what I neeeeed, oh baby..."I think it was a black group. The song had a little rap part in it too. HELP!

the group was called bvsmp (or b.v.s.m.p.)
i don´t know what this stands for...

Thanks a billion. I've been losing sleep at night wondering where I could get that song.
