Lovely Rita
The unusual noises during the song after the lines "and the bag across her shoulder/ made her look a little like a military man" were John Lennon, Paul McCartney, and George Harrison playing comb and paper. Mal Evans was sent to Abbey Road's lavatories to get toilet paper (which was stamped with the words, "PROPERTY OF EMI"). This was used to cover hair combs, which they blew through to sound like a kazoo orchestra.
