The Wisconsin native has won seven Grammys over a 50-year career. His biggest single was 1981’s “We’re in This Love Together.” Jarreau was a vocalist on the all-star 1985 track, “We Are the World,” and sang the theme to TV’s “Moonlighting.”

He is one of the few artists to have won Grammys in three separate categories — jazz, pop and R&B.

Jarreau is survived by his wife, Susan, and a son, Ryan.
