When head Foo Fighter Dave Grohl fell off the edge of the stage at a concert in Sweden earlier this month, dislocating his ankle and breaking his fibula, he finished the show, able to salvage the single gig. But, the band also had to cancel the remaining seven shows of their European tour.

Billboard speculates that the cancellation will cost the band about $10 million "in lost fees and travel expenses not offset by box office revenue." But, they suppose, the financial hit will be considerably harder if the band have to cancel shows on their upcoming North American tour, which is scheduled to start on July 4 in Washington, D.C., twenty years to the day from the release of the very first Foo Fighters album.
