Watch Foo Fighters & Rick Astley perform "Never Gonna Give You Up"

Yesterday in Japan at Summer Sonic Foo Fighters performed "Never Gonna Give You Up" with the one and only Rick Astley. Which ultimately meant their fans were Rick-Grohled... (sorry).

The song is actually a cover of a mash-up, which you can see here. Scroll on down to check out the cover/mash-up!
