Songfacts®:

• This is a novelty song based on a medley of traditional Mexican melodies. The Jarabe Tapatío was put together by Jesús González Rubio (c1804-74) who was Professor of Music at Guadalajara.
  
  The parody was recorded by the American comedian and song parodist Allan Sherman (1924-73) who adapted it with his collaborator Lou Busch; a live recording was released in the UK on the Warner Bros label in November 1963 as the B Side of "Won't You Come Home, Disraeli?"
• As the melody was already quite well known in the English speaking world, many people appear to have believed it to have been an authentic song rather than a parody. >>>
