"Abraham, Martin and John" is a song paying tribute to Abraham Lincoln, Martin Luther King Jr., John F. Kennedy, and Robert Kennedy, all of whom had been assassinated. The song was written for Dion, and would later have covers by Smokey Robinson and Marvin Gaye.
The song was referenced in the Dinosaurs episode "I Never Ate for My Father" by a folk singer at The Salad Bar, a hang-out spot for herbivores. His song, however, is about Bambi's mom.
