The band would not be required to perform in front of a segregated audience

Historic 1965 Beatles Contracts Signed by Brian Epstein -- The Beatles Demand That They Not Play for Segregated Audiences & Call on Venue to “…Supply Police Protection …of Not Less Than 150 Uniformed Officers…”
CONTRACT SIGNED

Very rare Beatles contract and rider dated 24 March 1965 for a concert to be given on 31 August 1965 at the Cow Palace in San Francisco, California. The concert was part of the Beatles’ coast-to-coast tour on their third major visit to the U.S., shortly after the release of “Help!” This interesting contract, between The Beatles’ management company Nems Enterprises, Inc. and Paul Catalana, calls for $40,000 “guaranteed against 65% of the gross box office receipts over $77,000.” The rider requires the venue to provide the Beatles with no less than 150 uniformed police officers for protection and a special drumming platform for Ringo, among other stipulations, such as the modest requirements for their trailer: “This trailer is to have electricity and water. In all dressing rooms for The Beatles, the purchaser must provide four cots, mirrors, an ice cooler, portable TV set and clean towels.” The rider also contains the provision that the band would “not be required to perform in front of a segregated audience.” Both contract and rider are signed on behalf of The Beatles by manager Brian Epstein. Contract together with rider are four pages, each measuring 8.5” x 10”, matted and framed to 22” x 28.5”. Some toning to contract page and staple holes in upper left corners of pages. Near fine.
