Come Together  is a song by the Beatles written by John Lennon but credited to LennonâMcCartney.
Lennon asked Leary if there was anything he could do to help his candidacy. The Learys wanted me to write them a campaign song, Lennon told Rolling Stone, and their slogan was 'Come together.' He knocked out what he called a chant-along thing, and Leary took the demo tape home and aired it on some radio stations.
