I don't think so, I would guess that they were custom made for him, but you could probably make a iron on transfer just like it if you wanted. Hope that helps!
Actually, I heard those tees were sold on the tour and Adam started wearing one each night...then they started selling out. I'm looking for one too! Its not on ebay...
i don't recall there being an orange one like in the photo, but i do know there was a black one, it was made for girls. i wanted to get one but i didn't have enough money for two tee shirts and a programme. (oh how naive i was, lol) so i never got one.
