We know Dave Grohl as the leader of Foo Fighters, the guy that banged on the drums for Nirvana and now also the special guest of Lionel Richie!
During Lionel's performance last night at the Rock & Roll Hall Of Fame Induction Ceremony, Dave came out and played the Commodores' song "Easy. Grohl has made it clear that growing up, he knew all of the songs on the radio and I'm sure he and his mom and sister sang "Easy" many times together.
Watch some videos from @FooFightersLive on Instagram and we'll get to see the show with Lionel and Dave and everyone with the Rock & Roll Hall of Fame Induction Special on HBO on November 19th!
