Dave Grohl of Foo Fighters on music after Kurt Cobain
Forty-nine-year-old Foo Fighters frontman Dave Grohl will go to any extreme, and won't let a little thing like a broken leg and dislocated ankle - suffered during a stage fall in Sweden - get in the way. The former drummer of the grunge band Nirvana talks with correspondent Anthony Mason about reentering music following the suicide of Nirvana frontman Kurt Cobain. Mason also talks with Grohl's Foo Fighters bandmates about keeping rock's flame burning.
