"All the Madmen" was originally released in 1971 (in the UK), and featured on Bowie's 1971 album The Man Who Sold the World.
Over the weekend, Sky Ferreira paid tribute to the late musician by wishing him a happy birthday with a cover of "All the Madmen".
Ferreira wrote that it's a "lost tape recording/demo", and added, "(I just found this btw)."
Her cover of "All the Madmen" marks Ferreira's first outing since teaming up with Charli XCX on "Cross You Out" in 2019.
Ferreira is yet to follow up her 2013 album Night Time, My Time.
