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.

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....

cd
Bing Crosby - "The undisputed best-selling artist until well into the rock era (with over half a billion records in circulation), the most popular radio star of all time, and the biggest box-office draw of the 1940s, Crosby dominated the entertainment world from the Depression until the mid-'50s"

check out his bio (and the others listed in this thread) on

you can also do some cross referencing hear for like artist to get started or to find more of something you already like...if this doesn't make sense it will when you see the sight.

cd
John Pizzarelli - does the classic pop songs (has an entire album devoted to Nat King Cole) - simple, smooth and enjoyable

John Feinstein - classic broadway musical stuff and the like - the real "classics" elegantly done.

Les McCann - earthy, jazzy stuff with more rhythmic drive.

Michael Franks - a little more personal, intellectual stuff, but has a nice pleasant voice and good arrangements.
