This is not a rickroll. I repeat, this is NOT A RICKROLL.

If you've ever wondered what Rick Astley might sound like singing the Foo Fighters song 'Everlong' (or any song other than 'Never Gonna Give You Up', for that matter), wonder no more.

The '80s star has covered the rock tune in preparation for a charity gig in London later this month, posting his rehearsal to Facebook and displaying some serious 'rock god' facial expressions in the process. "I'll be playing drums, not the guitar - so it'll sound a lot better than that," he promised. "Come and rock out with us, 23rd of December, Shepherd's Bush Empire". Presumably, for one night only he'll become 'Rock Astley'. Titter. (Sorry).
