Kids Incorporated

1989 (Season 6)

Stacy Ferguson (before she became "Fergie") and Jennifer Love Hewitt. Like The Naked Brothers Band, the kids of Kids Incorporated used their real names (with some exceptions) and sang stuff. However, the Naked Brothers Band also write their own songs, play their own instruments, and have maintained the same cast for more than 2 seasons. They also have much better plots. But when it comes down to singing alone, the kids on Kids Inc are pretty awesome.
