I get why HE would take advantage of the opportunity. I don't understand why a singing competition show would invite professional singers of this caliber (I know CM isn't HUGE, but I'm sure they listened to at least some of the music before inviting him, which is FAR AND AWAY enough evidence of his talent, not just to sing, but to create music). I've often wondered what would happen if Myles Kennedy stood in line to audition for American Idol. But I also think they wouldn't have him in the competition.
