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.

PS: I would like to add Tom Waits to the above list (though I always feel a little greasy while listening to him). I must be remembering his appearence on the Dinah Shore show.
Adamanteus & Kevziek, I just went back and read Kevziek's comment, and agree 100%. That's why my vote for the single, sole, only best singer of the 20th C is Merle Haggard. I did like William Bolcom (sp?) a lot. Opera singers are a dime a dozen. Real men who can interpret real men's songs are few and far between.
I dont know. I said my guess is Beniamino Gigli. Maybe somebody should send an Audiogon email to Tubegroover and ask him.
