Nilsson originally wrote this song at Paul McCartney's request for Mary Hopkin, an 18-year-old singer that McCartney had signed to Apple Records and whose first album, Post Card would feature her version of Nilsson's song.
David Cassidy released his version as a double A-side single with "Daydreamer", which reached No.
[1] In 1968, Nilsson went to London to meet with members of The Beatles after John Lennon named Nilsson as his favorite American artist with both Lennon and Paul McCartney naming him their favorite group, and they requested a session with him.
[2] While in London, McCartney asked Nilsson to write a song for Mary Hopkin, a request to which Nilsson complied, working out the song on the piano and recording a demo that night.
