Later uses
 Originally a waltz, during the British Dixieland Revival in the 1950s and 1960s this melody was often played in fast four/four tempo, notably recorded by the Kenny Ball Band. In the 2010 role-playing game Fallout: New Vegas, The Ink Spots rendition of the song can be heard playing on the in-game radio. A private recording exists of Elvis Presley singing part of the song over an orchestral recording by Nelson Riddle. In season 2, episode 4 of the New Zealand TV series Seven Periods With Mr Gormsby, Dancing with the Staff, the titular character Mr Gormsby performs a version of the song at the school dance.
