Al Jarreau, famed R&B and jazz singer died Sunday morning ... according to his reps.
The 7-time Grammy winner had been hospitalized recently in Los Angeles. Amid his medical battle ... he announced he would be retiring. He'd been touring almost non-stop for 50 years.
A message on his website says he passed away while in the hospital. The announcement doesn't say what he died from -- but Al had fought through respiratory and cardiac issues in recent years.
Just last week, Al's son said his father was singing "Moonlighting" to one of his nurses.
Jarreau won 7 Grammy's for a slew of hits through the '70s and '80s including "Mornin'," "After All, "We're In This Love Together" and, of course, that theme to the immensely popular "Moonlighting" TV theme.
