Why did they speed up Shake, Rattle, and Roll?

This is from the IMDB Trivia page:

"The song Yvette is dancing to in the beginning of the film, "Shake, Rattle, and Roll," is the version recorded by Bill Haley & The Comets, only it is sped up with the pitch increased. This trick was also used in Airplane! (1980), in which a sped of version of the BeeGees song "Stayin' Alive" is played."
