When looking back at the history of "Saturday Night Live," one musician has appeared more than anyone else, and that's Dave Grohl. Grohl has been a part of two of the biggest bands in music history — Nirvana and the Foo Fighters. Both of his bands have played the "Saturday Night Live" stage, including Nirvana during Grohl's first-ever performance on the show in 1992 (via Rolling Stone).
Grohl is also a part of the supergroup Them Crooked Vultures, which performed on the show back in 2010. In total, Grohl has appeared in the show 14 times (via SNL Archives). Outside of his own projects, he also played drums for Tom Petty during one of his "Saturday Night Live" runs. In a behind-the-scenes YouTube video, Grohl describes learning that Petty wanted him to play the show at the last minute. "Sweetest guy in the world, so much fun," Grohl said of Petty.
While his wheelhouse is music, Grohl has also shown his comedy chops in a few hilarious cameos in "Saturday Night Live" sketches. One 2013 "Saturday Night Live" skit takes place during a wedding when the father of the bride (Fred Armisen) decides to reunite his band. The group of former punkers relives their glory days in a performance that's shocking to their make-believe wedding guests. Grohl, Bill Hader, and Ashton Kutcher make up the rest of the band. "Hey, go easy on us guys, this is our first gig since like 1983," Grohl says while wearing a blonde wig.
