After tumbling off stage and breaking his leg in Gothenburg, Sweden last month, Dave Grohl has been playing Foo Fighters shows atop an elaborate light-up throne. Last night at Fenway Park in Boston, Grohl paid tribute to the man who fixed his leg, orthopedic surgeon Dr. Lew C. Schon, before inviting him on stage for a theatrical cover of the White Stripes‘ “Seven Nation Army”. Watch fan footage below, via Consequence of Sound.
