The all-star musicians who gathered this weekend to perform a very special cover of "Under Pressure" are no mere supergroup. In the words of throned frontman Dave Grohl, they're a "super-duper group."

Grohl, currently rocking out on Foo Fighters' Sonic Highways tour, tapped Queen's Roger Taylor and Led Zeppelin's John Paul Jones to join him onstage Saturday. Because the band's Milton Keynes Bowl concert took place on what would have been Freddie Mercury's 69th birthday, Grohl and company decided to honor the legendary singer by playing one of his best-loved songs — the 1981 duet that originally featured Mercury and David Bowie.

Seems like a pretty tall order — but as you'll see from the clip, Grohl and his pals didn't let the pressure get to them.
