Well, I like Tony a lot, too, but I think BT would be a much better match for JC's music (as far as we can guess from what we've heard). Also, let's face it: BT is a successful professional, acclaimed in his field. I have to think that touring with him would be perceived as a success for JC; possibly even a coup. Tony's still playing dive bars. That doesn't mean Tony's less talented, necessarily, but it does matter, particularly for an artist who isn't already established in his own right.
