You're most likely to find Rick Astley shimmying behind all of the internet links that seem a little too good to be true.
You're less likely to find him crooning at a Foo Fighters gig – and yet, that's what Dave Grohl fans were welcomed with at the band's headlining slot at the Summersonic Festival in Japan this weekend.
Half way through their gig, Grohl announced to the crowd that they had a special guest:
"Ladies and gentlemen, would you please welcome our new best friend, Rick Astley. This is fucking crazy. I just met him two minutes ago."
The band then began to play the opening riff of 'Smells Like Teen Spirit', before launching into 'Never Gonna Give You Up' instead.
