A contract and rider demonstrating both the political sensitivities and the relatively modest personal needs of The Beatles are to be auctioned.

In the documents drawn up ahead of a concert at the Cow Palace in Daly City, California, in 1965, the band stipulates it will not play in front of a "segregated audience".

It also requires the venue to provide "no less than 150 uniformed police officers for protection" and a "special drumming platform for Ringo [Starr]".

The requirements for their accommodation appear much less demanding than many modern artists. The band's trailer "is to have electricity and water", the rider says, adding: "In all dressing rooms for The Beatles, the purchaser must provide four cots, mirrors, an ice cooler, portable TV set and clean towels."

Signed by the band's manager, Brian Epstein, the documents are expected to fetch up to $5,000 (£3,170).

They are being sold by Los Angeles-based Nate D Sanders Auctions on 20 September.
