Kiddie duo Quo was signed to Michael Jackson's MJJ Music label in 1994 and released an album that begat a few not-bad singles.

Turns out, one half of the group, Wade Robson, grew up to become a big-time choreographer. Oh, and Justin's girlfriend at the time Britney Spears, and inspiring THE breakup song of breakup songs.
