"A tribute concert was held at the Barbican Centre, London on 10 May 2007 with Robyn Hitchcock, Captain Sensible, Damon Albarn, Chrissie Hynde, Kevin Ayers and his Pink Floyd bandmates performing (albeit not on stage at the same time)."

Is this footaged at all? I found one bootleg with David Gilmour and Richard Wright doing Arnold Layne.
