The lyric, "pretty nurse selling poppies from a tray" is believed to refer to Beth Davidson, who married Lennon's boyhood friend, Pete Shotton.

The reference to the barber, with "photographs of every head he's had the pleasure to have known," was later identified as James Bioletti, who used to cut the hair of Lennon, McCartney and Harrison when they were children.

The "banker in a motor car" on the other hand was invented by McCartney for the simple reason that it rhymed.
