The song A Hard Day’s Night was written by John Lennon and Paul McCartney and released by the Beatles in 1964 as a single and as the title track of their film and accompanying album A Hard Day’s Night. Sung mainly by John Lennon, the song reached No. 1 in both the UK and the US. It is famous for its distinctive opening guitar chord, played by George Harrison on a Rickenbacker 12-string guitar. The lyrics reflect the relief of returning home after a long day of work, matching the band’s hectic touring schedule at the time. The song became one of the defining tracks of the early “Beatlemania” period.
