It was first released on his album Imagine, and was later included in the greatest hits compilation Working Class Hero: The Definitive Lennon.

The song was written about his wife Yoko Ono, and features Nicky Hopkins on piano and co-producer Phil Spector on harmony vocal.

Lennon began writing the song in 1968 during the Beatles' visit to India, but was not fully completed until the sessions for Imagine three years later.

[5] An uncompleted version of the song can be heard and was recorded on tape at the Sheraton Oceanus Hotel in Freeport, Bahamas, on 25 May 1969.

[2] Stereogum contributors Timothy and Elizabeth Bracy rated it as Lennon's 9th best solo song, saying that "Few romantic ballads hit home as hard as 'Oh Yoko!,' a lilting testimony to enduring passion, every bit as melancholy as it is devotional.
