Dave Grohl broke his right leg during a performance in Sweden on June 12. Since then he and his band have had to make some changes in their touring schedule, their onstage performance and their daily routine. All the while, the frontman has also been busy rehabilitating his broken limb... in just about the the coolest fashion ever.

In a recent interview with Q magazine (as reported by Billboard), the singer reveals he’s written himself a hefty prescription for air drumming to help his recovery. “It's funny, ever since I started playing the drums my right calf muscle has been twice the size of my left from stomping the hell out of my kick drum pedal,” he explained. “Now, it looks like a sad little chicken wing so I've been doing a little bit of my own rehab therapy lately, which is air drumming along to Led Zeppelin three times a day."

While the Foo Fighters’ were able to make changes that let them keep most of their engagements after Grohl’s injury, one thing they had to cancel was their headlining gig at Glastonbury Festival. Florence + the Machine were moved to the top spot on the bill at the last minute, a decision with which Grohl completely agreed.

The frontman told Q magazine what happened when he e-mailed Florence Welch to congratulate her on getting their headlining spot. Welch, who broke her leg in February of this year at Coachella, gave Grohl some advice about healing his own injury and revealed that they'd be covering the Foo Fighters' song "Times Like These" during their Glastonbury set.

Grohl had a very emotional response to seeing a video of their cover. “The day after the gig, someone sent me a link to the performance and I cried like a f--king baby," he said. "It melted my f--king heart. I am forever indebted to them. It meant so much, you have no idea.” Check out a video of Florence + the Machine’s cover of “Times Like These” here.

Foo Fighters has been having an amazing time on their current North American tour. The band next play in Edmonton, Alberta, Canada on Aug. 12.
