Sir Paul McCartney is in top secret talks to perform the final show at San Francisco's Candlestick Park before the wrecking ball demolishes the sports mecca, according to U.S. reports. The Beatles performed their final Stateside concert at the former home of both baseball's Giants and football's 49ers in August, 1966, and now venue bosses are hoping McCartney will return for one final, historic show. The 53-year-old park will be demolished in early 2015. One Candlestick Park official tells the San Jose Mercury News that he "remained hopeful" that the former Beatles star would take the stage one last time, and Phil Ginsberg, general manager for San Francisco's Recreation and Parks Department, says, "Keep your fingers crossed. It's a possibility."
