Male Jazz singers - any recommendations?


I have a great appreciation for female jazz singers (Sarah Vaughan being my favorite). But when I was listening to a Horace Silver cd, lately (BTW: the RvG edition and some others are on sale right now at Towers for 9.99$), there was a male singer on the last track and it suddenly struck me, that I was completely oblivious of male jazz singers so far.
Now I'm looking for some recommendations. The Kind-of-Blue/My-Favorite-Things/Koeln-Concert-type of male jazz singer performances. Any suggestions are very welcome.

Check out Kurt Elling, Nat King Cole (Trio only) and early Louis Armstrong. Mr. Armstrong virtually invented jazz singing (just ask Billie Holiday).
Some repeats but it might be good to hear the names more than once.

Frank Sinatra (if you don't have "Sinatra I recommend Sinatra, Live at the Sands" with Count Basie -- remastered, pretty good recording great music)

Tony Bennett

Joe Williams (double cd Best of Joe Williams Live the Verve Years 2nd disc -- or "Every Day I Have the Blues" 1988 verve)

Nat King Cole

Luqman Hamaz - not well known but been around a long time recently recorded on Groove Note lable "Luqman Hamza, With This Voice"

Jimmy Scott

Charles Brown

Tom Waits (not Jazz exactly more folk/blues)

Louie Armstrong

Jimmy Durante (sp)

I would like to find others since I like Jazz/Blues voices so much....
