Guess the Fusion Rock Song Lyrics #63

*First line is the group name. 1982. This family of performers was from Michigan. The group name is their last name. There were 10 children altogether and every sibling was part of the group at some point. The 6th child, and typical lead singer, wrote this song. He sang part of the song in high tenor. This song propelled them to stardom. Janet Jackson was briefly and secretly married to one of these brothers before it was annulled.
