Alter Bridge / Edge
First off, let me just say that this is purely speculation so don't read anything into it.
But I was just watching WWE Raw, watching Edge vs. Randy Orton... and I got to thinking. The Tremonti's are good friends with Adam Copeland ("Edge"), and he's had the same theme music since he first started in WWE like, what, probably 4-5 years ago at least? Now, knowing about the relationship between Tremonti and Copeland, plus the promotion that WWE gave to Creed when My Sacrifice was coming out (all the "My Sacrifice" highlight deals that they did with various wrestlers)... I could see Edge using the new AB single whenever it comes out.
