Now and then

"Now and Then" is a song by The Beatles that was never officially released. It was written by John Lennon and Paul McCartney and was recorded during the late 1960s. The song is notable for its unique history, as it remains one of the band's rarest and most sought-after recordings. Despite numerous bootlegs circulating among fans and collectors, a polished version of "Now and Then" has never been made available by the band or its representatives. As a result, the exact key of the song remains unknown. However, some speculate that it may be in the key of C major, as many of The Beatles' compositions were written in that key. Although the melody of "Now and Then" is largely unknown, it is believed to possess the characteristic harmonies and melodic sensibilities that defined The Beatles' sound.
