On 29th January 1967, they recorded a number of songs at the Sound Techniques studios in West Hampstead, funded by Joe Boyd, co-founder of the UFO Club, and the band’s booking agent, Bryan Morrison. The tracks recorded included a version of “Interstellar Overdrive” and “Arnold Layne”, for which they also filmed a promotional video (seen below). Two days later they signed to EMI records for a £5,000 advance as The Pink Floyd.
On 11th March 1967, EMI released Pink Floyd’s first single with “Arnold Layne” on the A-side and “Candy and a Currant Bun” on the B-side, both written by Barrett. “Arnold Layne” managed to reach number 20 in the UK charts, in spite of some radio stations banning it because of the song’s rather risqué subject matter. The song told of the activities of a transvestite who acquired women’s clothes by stealing them from washing lines. Barrett based the Arnold on a real person who stole garments from the washing lines of his and Water’s mothers, both of whom took in female students as lodgers.
