Brain Damage (Pink Floyd song)

"Brain Damage" is the ninth track from English rock band Pink Floyd's 1973 album The Dark Side of the Moon. It was sung on record by Roger Waters (with harmonies by David Gilmour), who would continue to sing it on his solo tours. Gilmour sang the lead vocal when Pink Floyd performed it live on their 1994 tour (as can be heard on Pulse). The band originally called this track "Lunatic" during live performances and recording sessions. "Brain Damage" was released as a digital single on 19 January 2023 to promote The Dark Side of the Moon 50th Anniversary box set.
