The focus of the film is Syd Barrett, the lead guitarist of the early Pink Floyd, who created their unique psychedelic sound and most of the band's early songs, including the singles "Arnold Layne" and "See Emily Play" and much of their first album The Piper at the Gates of Dawn. Syd Barrett's name passed into rock folklore when he quit Pink Floyd in 1968 and, after two extraordinary but erratic solo albums, disappeared from music altogether amid rumours of a drug-induced breakdown. The Pink Floyd and Syd Barrett Story has contributions from Humble Pie drummer Jerry Shirley (who played on Syd Barrett's two solo albums The Madcap Laughs and Barrett as well as Syd's final London concert on 6 June 1970 with David Gilmour, when Barrett abruptly left the stage after playing only four numbers), bassist Jack Monck who played at Syd's last ever public concert in 1972 at the Cambridge Corn Exchange, producer Joe Boyd who produced Arnold Layne, photographer Mick Rock who photographed Barrett for The Madcap Laughs cover, and artist Duggie Fields who shared an apartment in London's Earls Court with Barrett in 1968 and witnessed his changing mental state at close hand. According to his sister, Barrett actually watched the documentary when it was broadcast on the BBC. He apparently found it "too loud", although he did enjoy seeing Mike Leonard, who he referred to as his "teacher". He also enjoyed hearing "See Emily Play" again.
