"If You Gotta Go, Go Now" is a song written by Bob Dylan in 1964. The first released version was as a single in the US by the UK group The Liverpool Five in July 1965, but this went uncharted in the US despite receiving much airplay, particularly in the Pacific Northwest. It was another English band, Manfred Mann, who then issued the song as a single in September 1965. This version reached number 2 on the UK charts.
Dylan began the recording for "If You Gotta Go, Go Now" on January 13, 1965, during the first session for Bringing It All Back Home. Of the two acoustic takes completed, neither was used. He recorded the song again on January 15, producing four takes. On May 21, 1965, producer Tom Wilson brought in several unidentified musicians to overdub various parts onto the takes recorded on January 15. From these overdubbing sessions, two takes were eventually released: take 5, released as a single in The Netherlands in 1967, and take 7, released on The Bootleg Series Volumes 1–3 (Rare & Unreleased) 1961–1991 in 1991.
Fairport Convention also took the song onto the charts, albeit in an unusual fashion: the group translated the song into French (partially, retaining the English "...you gotta stay all night" as the end of a line beginning in French for comic effect) as "Si Tu Dois Partir". Recorded for the Unhalfbricking album, the song was issued as a single in 1969. This was the band's only charting single, reaching number 21 and staying in the British Chart for nine weeks.
