Even though this song has no lyrics, the song has been dedicated to a group of miners who were caught in a tunnel collapse and while being rescued they asked for an iPod full of Foo Fighters songs.

Are you serious? That's awesome! This is a neat song.

Ya, adding to what James water said.

^^If you check this out, it's an interview on "the Hour" in which Dave and Taylor talk about some of the meanings of the songs off of the "Echoes, Silence, Patience and Grace", especially talking about Kurt and the start of the Foo Fighters careers. "For the longest time I wouldn't write lyrics that would be associated to something like that," refering to the death of Kurt. But he later goes in to explaining that now he isn't afraid to talk about it and write about it.

But now about the Ballad of the Beaconsfield Miners...

The song is about a group of miners who were in a mine collapse in Tazmania, in a town called Beaconsfield. When rescuers reached them with a drill, they could only give them small items. One of the miners (Brant Webb) asked for a I-pod with the Foo Fighters latest record on it (which was In Your Honor). Dave Grohl heard this story later and was playing in the area, so he invited the miner to come see the show and have a couple beers with the band afterwards. Well during the concert he played a little acoustic piece, which happened to be "The Ballad of the Beaconsfield Miners". Well, after the show, Dave had "a few to many beers" and promised to put it on the record, so he put it on the record. This is the true story, Dave said it himself.

Watch the video, it probably explains it better than I did, and it's an intresting video to any Foo Fighters fan.
