Alternate timeline
In an alternate timeline created by Lenny Kruger where the Common Men rose in place of the Beatles, Paul never pursued a musical career and was instead a clarke at a shipping office. He, however, knew the Common Men from a pub in Hamburg, and wanted to give them some of his songs. (AUDIO: 1963: Fanfare for the Common Men)
