Premise: Syd Barrett . Best known as a founder member of the band Pink Floyd , Barrett was the lead singer , guitarist and principal songwriter in its early years and is credited with naming the band . Barrett was excluded from Pink Floyd in April 1968 after David Gilmour took over as their new guitarist , and was briefly hospitalised amid speculation of mental illness . With Pink Floyd , he recorded four singles , their debut album ( and contributed to the second one ) , and several unreleased songs . Pink Floyd wrote and recorded several tributes to him , most notably the 1975 album Wish You Were Here , which included `` Shine On You Crazy Diamond '' , as homage to Barrett .
