I imagine Mr. Sinatra will have a comanding lead here. But (probaly intentionally) no category was mentioned. What about clasical (opera) singers? Anyone want to discuss Enrico Caruso vs. ?. What about comparing record sales? Is Elvis Pressly a contender because of volume of his record sales? Personally, I really like the jazz singer Johnny Hammond, especially his album with John Coltrane. Chet Baker, while I wouldn't EVER classify him as a great singer, had a distinctive way with singing jazz that was certainly unique, and very emotional. In sum, besides Hammond, I guess Francis Albert is the winner.
