David Gilmour has expressed regret over writing "You Know I'm Right," a vengeful song from his 1984 solo album About Face that criticised Roger Waters amid Pink Floyd's internal collapse. Frustrated by the difficult recording of The Final Cut and the band's unravelling, Gilmour used the track as an outlet for his grievances, though he later recognised this was a mistake. The song, which never named Waters directly but left no doubt about its target through lyrics like "Either you are wrong or I am right," captured the hostile atmosphere within the band at that time.

More than three decades after writing the track, Gilmour admitted to Mojo magazine in 2015 that airing such personal conflicts in song was "generally a poor idea" and that he would not repeat the approach. He acknowledged feeling tempted to let frustrations surface in his work, but recognised this reflected a misguided impulse to publicly resolve private disputes. The songwriter noted that whilst it is natural to grumble about injustices, channelling those complaints into permanent recorded form was unwise, particularly when it involved bandmate relationships.
