"Childhood's End" was performed live during Pink Floyd's European tour in late 1972 and at a few shows in March 1973 on their next North American tour. The live versions usually featured a fairly long instrumental section not found in the studio version, with an exception being the last version played on 10 March 1973 at Kent State University, when they stuck to the studio arrangement. The live versions were also performed in F-sharp minor, a step higher than the studio version (E minor).[citation needed]Nick Mason's Saucerful of Secrets resurrected the song for their 2019 and 2022 tours.[4][5]
