It was Aug. 27, 1965. The Beatles were on the eve of playing Balboa Stadium in San Diego. Elvis was in the midst of shooting “Paradise Hawaiian Style in Hollywood.”

That night, between 10 and 11 p.m., John Lennon, Paul McCartney, George Harrison and Ringo Starr arrived in limousines at Elvis’ home in Bel Air, and Elvis personally greeted them at the door for what forever after became known as the “summit meeting” of Pop music and Rock and Roll. ►
