The piano introduction was later used by Bob Dylan for his song "Temporary Like Achilles". The quick transition from G chord to a flat-III (Bflat) is unusual, especially as its F-natural note is melodically sustained against the following D-Major chord (with its concomitant F#) creating a "the most bluesy moment of the entire song." The verse opens with three repetitions of a simple four note motif ("Though you've gone away this morning, you'll be back again tonight") during which the chords mirror the lyrics in shifting from ii (Am chord) on "gone away" to IV (C chord) on "back again" to the tonic (G chord) on "tonight."
The song was recorded on 17 February 1965 in Abbey Road studio 2. It was one of the two songs on Help! written by Harrison, with the other being "I Need You." Help! was the first album since the 1963 release of With the Beatles to include songs written by Harrison.
It was covered by the band Glycerine on the album Harrisongs Volume 2 - A Tribute To George Harrison.
