Much of the track consists of tape loops that are faded in and out, several of which are sampled from performances of classical music. Works that have been specifically identified include the Vaughan Williams motet "O Clap Your Hands", the final chord from Sibelius' "Symphony No. 7", and the reversed finale of Schumann's "Symphonic Studies". Other loops include brief portions of Beethoven's Choral Fantasy, "The Streets of Cairo", violins from "A Day in the Life", and George Martin saying "Geoff, put the red light on". Part of the Arabic song "Awal Hamsa" by Farid al-Atrash is included shortly after the 7-minute mark. There are also loops of unidentified operatic performances, backwards mellotron, violins and sound effects, an oboe/French horn duet, a reversed electric guitar in the key of E major, loud cymbals and a reversed string quartet in the key of E-flat major. A loop from "Tomorrow Never Knows" is also evident.
