Pink Floyd: Dave Gilmour makes a surprise appearance at a Ben Watt show.

Pink Floyd guitarist David Gilmour made a surprise appearance last night with Ben Watt at London’s Islington Assembly Hall.

Gilmour has guested on the ex-Everything But The Girl’s new solo album Hendra, a collaboration with ex-Suede guitarist Bernard Butler – who also featured last night, performing three songs in Watt’s engaging set.

Towards the end of an enjoyable two-hour show, which highlighted a large part of his really good new folk-rock album, the amiable Watt (whose speaking voice is astonishingly reminiscent of Steven Wilson) began talking about meeting a musician at a party, who had offered him the chance to listen to their demos and ended up guesting on the album.

He then introduced Gilmour to the stage as he took his place behind a lap steel for a rendition of The Levels. Next the Floyd icon strapped on a trusty black Strat for a three way guitar duel with Butler and Watt for Young Man’s Game, his fluid notes easily identifiable and slicing through the electric atmosphere in the crowd.

Gilmour finally re-appeared for an encore of Spring before leaving Watt to end the night with a poignant Old Flame.

It marked a rare return to the public spotlight for Gilmour, who has been busy working on his fourth solo album, a follow-up to 2006’s hit record On An Island, slated for a possible late 2014 release.
