The limited-edition, one-sided Record Store Day 7" vinyl represents the last live performance of Pink Floyd with David Gilmour, Nick Mason and Richard Wright all together in 2007. This special performance of Arnold Layne took place at the Syd Barrett Tribute Concert - 'The Madcap's Last Laugh' (produced by Nick Laird-Clowes with Associate Producer Joe Boyd) held at The Barbican on 10 May 2007. The Pink Floyd members were augmented by Jon Carin (Keyboards, vocals) and Andy Bell from Oasis on bass guitar. After a star-studded line-up throughout the evening, Pink Floyd took to the stage for an incredibly emotional finale.
