Cabell "Cab" Calloway III was a jazz singer and bandleader, well known for his performances at Harlem's Cotton Club and scat singing.
His music was worked into several of Fleischer Studios' Betty Boop cartoons, including "Minnie the Moocher", in which Calloway provided the voice for a spectral walrus.
That's right, a spectral walrus. You can't make this up. At least, I can't.
He created music that people loved, and that is worthy of some appropriate memorial. Like a crater on Mercury, where they name craters after artists.
