Tattoos' reminds me of where I'm from, and some of the stuff I did when I was growing up. That was one of the things that was appealing about the song when I heard it the first time.

The worst gig story I have is from a club in Alabama that I think is still up and running, so I won't name the name of the club. We got hired in there to play, and the owner was pretty annoying. He kept coming up to me during the show and asking me to play 'Purple Rain.'

We call them impact songs, and people buy impact songs. But you just never know what those songs are going to be. One of those songs that really went through the roof for us was 'Big Green Tractor,' which I thought was kind of a fun little ditty song that I never in a million years thought would be as big as it was. But it was.

For every album, I look at where I'm at in my career and think of a title that kind of represents that. And for me, 'Night Train' was kind of a metaphor for where things have gone, from being on one bus with 12 other guys, pulling a trailer my first few years on the road, to now. We're out here with six or seven buses and eight or nine semis.
