It's influenced a lot by Led Zeppelin and anything from that era really. Before the album, when I actually wrote it and showed Ben and Chris, Ben and Chris liked it and they wanted to continue working on it and write a bit more, and I didn't really like the song. And they were like, 'oh, come on, we'll just use it' and so I said, 'yeah all right,' just to see how it would turn out. And it ended up changed a little bit and now I'm really happy with it.
