Notice
This is a good-time feel and catchy melody tune. The bridge takes the standard circle of fifths chord progresion of the jazz era and stands it on its head by making it a circle of fourths or upside-down fifths.
It seems that Ellington was in a taxi with Nick Kenny, a well-known columnist for the Brooklyn Eagle newspaper, crossing the George Washington Bridge after a benefit concert. Kenny asked Duke where he was going; Duke replied,"Drop me off at Harlem." Nick suggested that his response would make a good title for a song. And how this piece came to be.
