The Piedmont Conservancy that cares for the city park said Wednesday that the 67-year-old ex-Beatle will perform in the park on Aug. 15.
The show is expected to dwarf the conservancy's 2007 Dave Matthews Band and The Allman Brothers Band show that attracted 50,000.
Money raised goes to maintaining and expanding the sprawling and heavily used park in the shadow of Midtown Atlanta's skyscrapers. The park dates back to a private club founded in 1887.
