Irving mills, duke ellington

What good is melody, what good is music
If it ain't possessin' something sweet
It ain't the melody, it ain't the music
There's something else that makes the tune complete

It don't mean a thing, if it ain't got that swing
It don't mean a thing, all you got to do is sing
It makes no diff'rence if it's sweet or hot
Just give that rhythm ev'rything you got
It don't mean a thing, if it ain't got that swing
