Frank Sinatra & Nat King Cole  Two equally splendid versions of " That's All'"  Allan Brandt and Bob Haymes wrote this lovely ballad first made famous by Nat King Cole although Sinatra foll0wed with a fine version.Both singers mastered the art of elegant phrasing, clear articulation and interpretive sensitivity.
The string arrangement by Dob Costa for Sibatra is especially engaging.
