“Jingle Bells,” The Singing Dogs, 1955

Today, this tune is dismissed as a kitschy novelty song, but it was actually an experiment from the early days of tape recording. Recording engineer Carl Weisman would routinely have his birdsong recordings ruined by barking dogs, so he spliced the barks together, tweaked their speed and pitch, and made music with them with assistance from record producer Don Charles.  This was before the advent of modern editing equipment, so it took some effort.
