"Letting Go" is a song credited to Paul and Linda McCartney and originally released by Wings on the 1975 album Venus and Mars. The song was remixed and released as a single on 4 October 1975 in the United States, and on 18 October 1975 in the United Kingdom. The song peaked at number 41 in the UK, and a slightly better number 39 in the US.
The song was recorded late in 1974 at Abbey Road Studios, before the band went to New Orleans to record the bulk of Venus and Mars. It was one of only three songs recorded with short-term Wings' drummer Geoff Britton before Britton quit the band (the others being "Love in Song" and "Medicine Jar").
Like many of Paul McCartney's songs of this period, the subject of "Letting Go" is his wife Linda. The singer describes himself in a relationship with a beautiful woman but he remains concerned about the relationship. McCartney biographer Peter Ames Carlin claims that the song "traced the thin line between love and obsession", with "passion in all its unhinged, dangerous glory." The song reflects McCartney's recognition that he needed to give his wife more space to pursue her own interests, after Linda had given up her career as a photographer to join his band. The content of the lyrics varies between the verses and refrain, with the verses describing the subject and the refrain acknowledging the idea of "letting go." The key is A minor at the start of the song, but the song ends in C minor.
