Alternate timeline
In an alternate timeline created by Lenny Kruger in which the Common Men rose to prominence in place of the Beatles, Starr never pursued a musical career. Unlike the other potential Beatles, however, he was not enlisted in the British Army as part of national service due to health problems. (AUDIO: 1963: Fanfare for the Common Men)
