"Taxman" is a song by the English rock band the Beatles from their 1966 album Revolver. Written by the group's lead guitarist, George Harrison, with some lyrical assistance from John Lennon, it protests against the higher level of progressive tax imposed in the United Kingdom by the Labour government of Harold Wilson, which saw the Beatles paying over 90 per cent of their earnings to the Treasury. The song was selected as the album's opening track and contributed to Harrison's emergence as a songwriter beside the dominant Lennon–McCartney partnership. It was the group's first topical song and the first political statement they had made in their music.

"Eleanor Rigby" is a song by the English rock band the Beatles from their 1966 album Revolver. It was also issued on a double A-side single, paired with "Yellow Submarine". Credited to the Lennon–McCartney songwriting partnership, the song is one of only a few in which John Lennon and Paul McCartney later disputed primary authorship. Eyewitness testimony from several independent sources, including George Martin and Pete Shotton, supports McCartney's claim to authorship.
