Foo Fighters brought a well-known Internet meme to life on Sunday at the Summer Sonic Festival in Tokyo, Japan.
The band "Rickrolled" the crowd by unexpectedly bringing the real Rick Astley on stage to sing "Never Gonna Give You Up" with them. As Astley walked on stage to front the band on his greatest hit, Dave Grohl said, "This is [blankin'] crazy. I just met him two minutes ago."
There's video of the performance up on YouTube, but I have to warn you that both Grohl and Astley let fly with some words you won't want your kids or fellow workers hearing at the very top of the clip.
