 Barrett made a final public acknowledgement of his musical past in 2002, his first since the 1970s, when he autographed 320 copies of photographer Mick Rock's book Psychedelic Renegades, which contained a number of photos of Barrett. Rock was perhaps the last person in the music industry with whom Barrett kept in contact. In 1971, Rock conducted the final interview of Barrett before his retirement from the music industry a few years later, and Barrett subsequently turned up on Rock's London doorstep "four, maybe five times" for a cup of tea and conversation through 1978, before Barrett moved back to Cambridge. They had not spoken in more than twenty years when Rock approached Barrett to autograph his photography book, and Barrett uncharacteristically agreed. Having reverted to his birth name "Roger" from his stage name "Syd" many years before, he had autographed the book simply "Barrett."
