McCartney Times

The Beatles had only been in America for 11 days when they found themselves herded into Miami Beach’s 5th Street Gym for a photo op with a 22-year-old boxer named Cassius Clay. It was February 18th, 1964, and the band was in town to film their second appearance on the Ed Sullivan Show. Clay was prepping for his big fight with Heavyweight Champion Sonny Liston, but he was a 7-1 underdog and anxious to drum up ticket sales and press attention.
