Dave Grohl to make good on pledge to trapped Tasmanian miners.

When Australian miners Brant Webb and Todd Russell were trapped almost a kilometre underground, they listened to country music and American rock band Foo Fighters.

In May, lead singer Dave Grohl heard of their plight and promised to get them tickets and a beer when they got out safely. Now he can make good on his pledge, with the announcement of two Sydney concerts in October.
