The One I Love (Belongs to Somebody Else)

"The One I Love (Belongs to Somebody Else)" is a song that Frank Sinatra recorded for his 1959 Capitol album, No One Cares. This recording wasn't featured in the original album and was cut from release to be released as a single instead. It was later re-recorded and featured in the 1961 Reprise album I Remember Tommy....

Lyrics
You know the one I love belongs to somebody else, That's why she sings her songs to somebody else, And even when you have your arms around her You know her thoughts are with somebody else, And when I hold her hand they belong to somebody else

And you can bet they're not so cold to somebody else, It's tough to be alone on a shelf, And it is worse to fall in love by yourself When the one you love belongs to somebody else.
