The Philipines, June 1966
The Fab Four left hordes of crazed teenage girls in their wake for years, but their biggest disturbance occurred when a first lady wanted to smash. In 1966, the band was on tour in the Philippines and declined an invitation to lunch from that nation's president's wife, Imelda Marcos. The result of such a culturally rude gesture was widespread rioting in the streets. The group was forced to essentially flee the country without any official security and were nearly killed in the process, eventually prompting them to quit touring that year.
