On 16 June 1967, Pink Floyd released their second single, "See Emily Play" on the Columbia label. Written by original frontman Syd Barrett, it was released as a non-album single but appeared as the opening track of Pink Floyd, the US edition of the band's debut album The Piper at the Gates of Dawn (1967).
The song was written by Barrett following the Games for May concert and became a top 10 hit when released in the UK the following month. The group appeared three times on Top of the Pops, where Barrett started showing signs of erratic behaviour, which ultimately led to him leaving the group in early 1968. Although Pink Floyd seldom performed the song live, it has been recorded subsequently by at least seven diverse artists and regarded as a classic psychedelic pop single.
