On connaît la chanson
Several off-key, a cappella versions of "Yesterday" are dispersed throughout the record, alongside Lennon's "Happy Christmas to Ya List'nas", "Auld Lang Syne" (which briefly morphs into an impression of Barry McGuire's "Eve of Destruction"), a one-and-a-half-line version of the Four Tops' "It's the Same Old Song" (which they quickly stop before they violate the copyright), and an original poem titled "Christmas Comes But Once a Year".
