Being Rick-Rolled by the FOO FIGHTERS is cool. Being Rick-Rolled by the Foo Fighters AND RICK ASTLEY? Priceless!
The Foo Fighters were playing the Summer Sonic Festival in Japan, and Rick just happened to be on the bill as well . . . so they decided to make some MAGIC together.
They brought Rick onstage, and proceeded to rip into "Never Gonna Give You Up" . . . but they played the chords in the style of "Smells Like Teen Spirit". It was fantastic.
