• Although Burton Lane was neither the most prolific nor the most talented of songwriters, he gifted the world one song with a delicious title that literally trips off the tongue, or his lyricist did.
  
  The song with the longest ever title to appear in any Hollywood film was written by the pair for the 1951 musical Royal Wedding (known in the UK as Wedding Bells). The show was based loosely on the screen partnership of Fred Astaire and sister Adele, and was performed by Fred with Jane Powell during a comedy dance routine. Although by this time Astaire was on the wrong side of 50, he could still move with the best of them, and it is probably no insult to Lane and Lerner to say the choreography outshines the song, whose title would have been even longer if Lerner had included the grammatically correct questionmark! >>>
