Newly revealed police records give fans a chance to revisit The Beatles' first weekend in America.
Logs kept by New York officers assigned to protect the Fab Four in February 1964 have been donated to Liverpool's Magical Beatles Museum.
The handwritten pages were obtained by NYPD officer Patrick Cassidy. He tells the BBC, "One day in 2013, I went into the storage area that holds these books... After 50 years, they clean out and destroy them, so I looked up February '64 and found the book, which would have been destroyed the following year."
The entries note that The Beatles were "well dressed and well behaved." On the day of their famous Carnegie Hall concert, February 12th, 1964, an officer was "knocked off balance" and injured outside the Plaza Hotel while "attempting to restrain the surging crowd."
