During the Foo Fighters’ show at Boston’s Fenway Park Sunday night, Dave Grohl’s doctor joined the band onstage to lead a cover of the White Stripes’ classic “Seven Nation Army.”
Dr. Lew C. Schon has been caring for Grohl ever since he broke his leg onstage last month in Sweden. In the above clip, you’ll see Grohl accompanying his doctor from the safety of his light-up guitar throne (which he apparently dreamed up while on morphine in the hospital.)
“Holy s–t, that’s actually my doctor,” Grohl said after Schon left the stage. “What a badass.”
