The pair made a surprise appearance at the launch of Club NME, at Hackney's Moth Club in East End on Saturday (NZT).

The former Nirvana drummer then introduced Astley to the audience as he took to the front of the stage to finish the song to rapturous applause.

The duo also performed a version of the Foo Fighter's 1997 hit song Everlong, from the album The Colour and the Shape.
