David Bowie made a surprise appearance at the Royal Albert Hall on Monday, arriving onstage for the encore at a gig by former Pink Floyd man David Gilmour - marking Bowie's first appearance on a UK stage for nearly two years. The singer received a standing ovation after performing 'Arnold Layne' and 'Comfortably Numb'.
David Crosby and Graham Nash also guested on Monday, performing on, amongst others, the title track from Gilmour's recent album release 'On An Island'. Gilmour plays the last of his sold-out three night residency at the venue tonight.
