Over 50 years ago, on August 15, 1965, John Lennon, Paul McCartney, George Harrison, and Ringo Starr took the stage at New York City’s Shea Stadium for the concert of a lifetime. The Beatles kicked off their 1965 tour, which would continue on to Toronto, Chicago, and Los Angeles, among other stops, with the Shea show, breaking attendance and financial records.
