In addition to judging the world class competition, Grohl took photos with barbecue celebrities like the Food Network’s Danielle “Diva Q” Barnett, who was on site as a member of Team Traeger Grills. He also jammed out with “This Bear Came To Party” and “Hillbilly Rich” singer Tim Montana, who joined Grohl for a “House of the Rising Sun” cover that saw found the former Nirvana drummer banging away on the cajón. Dave Grohl is the kind of guy who finds the time to perform with his daughters in the midst of a world tour—which is to say, Dave Grohl is the kind of guy who rarely takes a break. Consider this past weekend for example. Instead of using his brief time off the road to lounge around a pool or something, the Foo Fighters frontman made his way to the Memphis in May World Championship Barbecue Cooking Contest, where he served as a judge and hung out with the competitors. Grohl will hit the road against next month when the Foo Fighters head to Europe for a three week outing. After that, the band will return to the United States for a lengthy stadium/arena tour, including a two-night stand at Chicago’s Wrigley Field.
