In case you didn't know, the Motor City Machine Guns and Petey Williams are part of a rock band called The High Crusade. They recently came out with a new CD called, "It's Not What You Think." I listened to some of the tracks, and I think some of the songs are pretty good! (Shelley is the singer, Sabin plays bass and Petey is on guitar.)
I think some of the songs might be good for official PPV songs. I think it might be a good way for TNA to help out their best tag team.
Here's their website, where you can listen to the songs:
