I suppose if you didn't know who JGJ was, there the interest on whether he's returning isn't a big deal.
Most visable? Doubtful, other than his guest starring on Glee, I don't think he's done much to garner name/face recognition. (I don't think thats bad, because it truly seems that kid truly thinks about the vehicle, not stardom.)
However, I think I'd be hard pressed to say whether I thought Gallagher or Groff had the strongest future possibilities.
If we're not having fun, then why are we doing it?
