Grohl has always been fond of throwing some cover songs into his live shows with the Foos, so the excited crowd couldn't have been that surprised when Grohl started playing Rick Astley's 1987 hit "Never Gonna Give You Up" amid calls for the Foos' 1997 hit "Everlong."
The former Nirvana drummer reportedly told RadioX on his way to the stage that he had "no f---ing clue" what he was going to do. That proved to be a bit of a work, as Grohl was joined by Astley himself after the first chorus of "Never Gonna Give You Up."
Grohl and Astley have been friendly for at least a few years; they performed together with the Foo Fighters in 2017.
Astley is a noted hard rock fan, who in addition to performing with the Foos has been known to cover AC/DC during his own live concerts.
