"Dark Side of the Moon: A Piece for Assorted Lunatics", as it was then known, was performed in the presence of an assembled press on 17 February 1972 more than a year before its release at the Rainbow Theatre, and was critically acclaimed. Michael Wale of "The Times" described the piece as "bringing tears to the eyes. It was so completely understanding and musically questioning." Derek Jewell of "The Sunday Times" wrote "The ambition of the Floyd's artistic intention is now vast." "Melody Maker" was less enthusiastic: "Musically, there were some great ideas, but the sound effects often left me wondering if I was in a bird-cage at London zoo." The following tour was praised by the public. The new material was performed in the same order in which it was eventually sequenced on the album release; differences included the lack of synthesisers in tracks such as "On the Run", and Clare Torry's vocals on "The Great Gig in the Sky" being replaced by readings from the Bible.
