Cage the Elephant were in danger of missing their opening slot for Foo Fighters in Salt Lake City last night after their drummer's appendix burst. Luckily there was a pretty kick ass drummer already there and willing to sit in for a few songs -- Dave Grohl.

Dave Grohl made a name for himself beating the skins for Nirvana, and still occasionally plays in the Foo Fighters' off cycles -- most recently for Them Crooked Vultures. Though Dave fronts one of the world's biggest rock bands, he is still well respected (and rightfully so) as a rock drummer.

So when the Kentucky alt-rockers Cage the Elephant found their drummer Jared Champion hospitalized for appendix issues just hours before the show, Dave volunteered his services so they could still open for his band. A few songs into their set with a substitute drummer, Grohl made his way to the stage and finished out the last five songs of the set.

Cage the Elephant vocalist Matthew Shultz thanked Grohl for his selfless favor and said the experience was, "one of those moments I’ll never forget for the rest of my life." After the set Dave still took to the stage in front of the Foo Fighters and rocked an energetic two-hour plus set. Cage the Elephant again thanked Dave and the Foo via Twitter saying:

"Crazy Crazy day!!!!!! HUGE thanks to Dave Grohl for jammin the drums!! Having a great time on Foo Fighters."

Cage the Elephant has not canceled any of their remaining dates with Foo Fighters, but there is no word as to who will fill in on the kit until Champion recovers.
