Yes! I read not long ago that Wynton's salary from JALC is $1 million per year.
Not bad...
What about Wayne Shorter, Herbie Hancock, and Keith Jarrett?
The richest? I think it was Ellington and second Lionel Hampton. He has built a neighborhood for the poor.
He had no children only a half-brother, Sammy Davis, Jr.
