The genius of the songwriter is as important as the singer himself.
The melody as well as the lyrics are important. Why are lyrics like "I love you yeah, yeah, yeah " so utterly common place?
The singer is ofcourse important too in the way he interprets the song writers song.
All the songs sung by FS have also been sung by many other singers, but Sinatra's songs linger in your memory and haunt your senses much more because of his intimate interpretation of the music & the lyrics. So, why do I always get this feeling that this song was written only for Sinatra, even though others may sing it as well?
FS's interpretation of the lyrics of the likes of Cole Porter, Rogers & Hart, Irving Berlin, the Gershwins, Johnny Mercer, Johnny Burke, Harold Arlen, Jimmy Van Heussen, Rube Bloom, Jules Styne, Jerome Kern & ofcourse Sammy Cahn (who was known to have the reputation of being Frank's personal lyricist) are history.
So are some of the songs of McKuen, Sammy Fain (the "I'll be seeing you" guy), Ebb & Kander, Cy Coleman & Carolyn Leigh, Billy May, Miller, Murden & Maria & ofcourse A.C. Jobim (whose accompaniment with FS left FS feeling he had a permanent hoarse voice) brilliantly rendered by FS.
Every song sung by FS has its own unique stamp which no one can ever imitate.
Even Sammy Davis Jr. who was dubbed many times as being a clone of FS was unique in his own way.
The songwriter & the singer "go together like a horse & carriage."
FS sure picked the right songs & the right lyrics to interpret his feelings
