Paul McCartney has announced two new performance dates, the first at San Franciscos very own AT&T Park on Saturday July 10th, and then at the Rio Tinto stadium in Salt Lake City on Tuesday July 13th, as part of his Up and Coming 2010 tour. Keeping with his headline-making special concerts over the last few years, the tour will see the iconic star and his band play unique venues, places and locations; new cities hes never played and familiar markets hes not visited for a while.
