 Apart from a brief encounter between Waters and Barrett in Harrods a couple of years later ( during which , when Barrett saw Waters he ran outside , dropping his bags full of sweets in the process ) , this was the last time any member of Pink Floyd saw him . A reflection on the day appears in Nick Mason 's book Inside Out : A Personal History of Pink Floyd . A reference to this reunion also appears in the film The Wall , where the character Pink , played by Bob Geldof , shaves his body hair after having a mental breakdown , just as Barrett had .
