Best Male Singers of the 20th Century


There is an interesting current discussion about the best female vocalists on CD. I have my own ideas about the best male singers (any category) of the 20th Century, but would like to hear other opinions.

He may not be the best "Male Singer of the 20th Century' but the latest album by Andy Bey "American Song" sure is good. Give it a listen, see if you agree.
How about Johnny Hartman or Kevin Mahogany? Just listen to "John Coltrane and Johnny Hartman" or "Monk on Monk" By TS Monk, for a couple of great examples of what these masters could do.
I will exclude Opera and Broadway singers. My list would include singers and singer song writers:
Sinatra,Crosby,Armstrong,Mathis,Sammy Davis Jr,Tony Bennett,Bobby Darin, Ray Charles,Bobby Short,Orbison,Elvis,John and Paul, Simon and Garfunkel, James Taylor and Billy Joel.
