Dick Parry played the sax solo on "Money.

It was Dick Parry, a session saxophonist who had also played on earlier Pink Floyd records. He was a friend of the band, not some hired gun from a studio pool.

The recording was deceptively simple. Engineer Alan Parsons miced Parry’s tenor sax closely in the studio, ran it through a touch of reverb (the Abbey Road echo chamber), and that’s it. No effects, no overdubs, no trickery. Parry played it live with the band, and they kept the first or second take. The solo sounds so relaxed because Parry was just a guy who knew how to blow a blues line without overthinking it.

That solo is probably the most recognizable saxophone moment in rock history, and it was recorded in one room with one mic and one player who didn’t try to impress anyone.
