Paul McCartney plays Rio Tinto stadium tonight (July 13).
I'm sure his merchandise tables will be packed with fans buying a T-shirt, hat, program and/or other memorabilia.
But there's a chance for fans to receive a free T-shirt.
McCartney, a vegetarian, informed the Salt Lake media by way of a press release, to tell fans to mention his "Meat-free Mondays" campaign. If they do that at the merchandise tables, they will be eligible for a free T-shirt.
I'm not saying that everyone who mentions the campaign will automatically get a free T-shirt, but some will.
