A kids' song, a Ringo song, a comforting peaceful song. Octopus's garden recalls childhood car rides. Even Mike heard this one as a kid, although he learned the Raffi version first. It's a simple 1, 6, 4, 5 progression with a simple major pentatonic riff to begin. There is strength in the simplicity. At the end of the episode, Mike and Dave try a punk rock reprise with faster music and harsher vocals, just for fun.
