Herb Jeffries is best known as a romantic singer from the days of WWII. His singing on "Flamingo" pushed the song to legendary status, selling millions.

Calling him Black is a bit of a stretch. He is about 1/8 Ethiopian (its a long story) and has features like the average Portuguese, Greek or Italian, not Black.

I say "is" because he still resides with his wife in California at about 99 years of age (give or take a few, it's a long story).

His "The Bronze Buckaroo" persona dates clear back to 1937, rather early in the Cinema Cowboy Era.

There is a CD of his singing from the late 1990s, perhaps on Rounder, not sure.
