John Lennon Anthology is a four-CD box set of home demos, studio outtakes and other previously unreleased material recorded by John Lennon over the course of his solo career from "Give Peace a Chance" in 1969 up until the 1980 sessions for Double Fantasy and Milk and Honey. The anthology was divided by its compiler and co-producer, Yoko Ono, into four discs representing four eras in Lennon's solo career: "Ascot", "New York City", "The Lost Weekend" and "Dakota". John Lennon Anthology reached number 62 in the United Kingdom and number 99 in the United States, where it went gold. A one-disc distillation of the highlights of the box set was released as Wonsaponatime. Many of the tracks were edited down from their versions on John Lennon Anthology. Wonsaponatime failed to reach the US charts but peaked at number 76 in the UK.
