Foo Fighters "Seven Nation Army" (White Stripes cover) (live video)
If you've been able to see the Foo Fighters this summer, chances are the concert was a memorable one. Frontman Dave Grohl broke his leg early in the summer, forcing the band to cancel some shows — but they're currently powering through with Grohl performing every night atop a custom-made throne to support his injured leg.
 
And while the band have still had to contend with other obstacles like shitty weather, their show in Boston last night (July 19) went off hitch-free and even featured a special guest.
 
For a rendition of the White Stripes' "Seven Nation Army," Grohl and his fellow fighters of foo brought out the foot doctor that's been travelling with the band in recent weeks. Dr. Lew C. Schon didn't just make an appearance; he stole the show with his wailing vocals and spirited moves.
