The first rough recordings of the song, including some of the sound effects, were recorded in a small recording studio Roger Waters had in his garden shed. As recorded by the band, the song has a sad feel, unlike Waters' original version, which he later talked about as "prissy and very English". As heard on "", the demo is in G-sharp minor, as opposed to the B minor of the final version. The instrumental section was worked on by both Gilmour and Waters, with Gilmour overseeing the time change as well as his own guitar and voice work, and Richard Wright and Nick Mason making up their own parts. Dick Parry added the tenor saxophone solo that comes before the guitar solo. Gilmour's advice is also seen in the final mix, which features "wet" and "dry" sections. To produce the special high notes that make up the final chorus of his solo, Gilmour played a special Lewis guitar with twenty-four frets, allowing a large variety of notes.
