The Beatles Play to 18 People.

“Sam Leach, The Beatles’ then agent, and wanting to become their manager, attempted to introduce the group to London agents by promoting a gig at The Palais Ballroom, Aldershot, on 9th December 1961. The show was not advertised properly and, as a result, only 18 people attended. Weeks after this Brian Epstein became the group’s manager.”
