“She’s Leaving Home”  is a Lennon–McCartney song, released in 1967 on the Beatles album Sgt. Pepper’s Lonely Hearts Club Band.  Paul McCartney wrote and sang the verse and John Lennon wrote the chorus, which they sang together.  Neither George Harrison nor Ringo Starr was involved in the recording.  The song’s instrumental background was performed entirely by a small string orchestra arranged by Mike Leander, and was one of only a handful of Beatles songs in which the members did not play any instruments on the recording.  (More from Wikipedia)
