official. As The News posted last Friday, Paul McCartney will indeed perform the very first shows at The Mets' new home, Citi Field, on July 17th and 18th. The shows will mirror McCartney's historic performance with the Beatles at the team's former home (Shea Stadium), which was the first music event ever held there, back on August 15, 1965. Forty-three years later, McCartney performed at the final show at Shea, as a guest star for Billy Joel's run there in July of last year. "I am really excited about playing Citi Field. The Beatles were the first to play at Shea Stadium and along with Billy Joel, I was the last to sing at the old Shea,” Paul McCartney said in a press release. "So, to be the first to play this stadium is incredible. I am really looking forward to a buzzing show." The original Shea performance (which was followed by another by the Beatles in 1966) was the first time in history that a sports stadium was used for a rock concert. The show set new attendance records at the time, with 55,000 screaming fans in attendance, establishing a new benchmark of popularity for rock. In the years since, a range of top musicians played Shea, including The Stones, Bruce Springsteen, The Who, and Simon & Garfunkel. Tickets for McCartney's show go on sale Monday, June 15 at 10:00 A.M. EST online exclusively at www.507TIXX.com and by phone at 718-507-TIXX. The concerts are rain or shine. Rumor has it a third show may be added, to take place on July 21st.
