ABC/Fred WatkinsDave Grohl loves playing with his other artists, especially his heroes, though his collaborations are usually in the same zip code, musically. So what happened this weekend might surprise a lot of people.

Stereogum reports that at Japan’s Summer Sonic Festival, Foo Fighters played the Marine Stage while ’80s phenomenon Rick Astley performed on the Mountain Stage. A more unlikely collaboration could not have been predicted, but leave it to Grohl to come up with something fun on the fly.

Having only met two minutes prior, they got together during the Foos’ headlining set to perform a rocked-up version of Astley’s worldwide hit “Never Gonna Give You Up.”

Video has surfaced online and Grohl seems positively giddy, saying “This is f****** crazy! I just met him two minutes ago!” As Grohl and the band start up the song, Astley shed his clean cut image and shouted, “Come on you mother******!”

Rickroll, that!
