For decades, they were tucked away in a tour manager's duffle bag... more than 50 candid photographs of the Beatles and the Rolling Stones taken during each band's first American tour.
The photos, taken by tour manager Bob Bonis, will be part of an exhibition titled "The British Are Coming: The Beatles and The Rolling Stones 1964–66," at New York's Not Fade Away Gallery.
