DR Jennifer - Josiah has made the rounds of "Access Hollywood", "Extra", etc., here in the states. He has now revealed his mother's fight with cancer, and how he wants to make her proud before she dies.
He was also on "Ellen", and she gave him $8,000 worth of musical equipment, and, apparently, some real estate company is trying to set him up with some real housing (instead of his car)... I'm sure if you go to each program's websites and/or YouTube, you should be able to find the clips of his appearances.
I may be totally misreading him, but, right now, he seems to be really playing into being in the spotlight. His tears still seem genuine, but that English-inflected Tennessee accent is really getting annoying. -To me at least.
