Short answers, pulled from the story.
Allan Richard Williams, born on the 21st of February 1930, was the original booking agent and first manager of the Beatles. He drove the band to Hamburg, West Germany in August 1960 in his Morris J2 van and helped secure their early bookings, including a tour of Scotland backing singer Johnny Gentle.
Williams stepped back from managing the Beatles in late 1960, distracted by the burning of his Top Ten Club and the planned opening of the Blue Angel nightclub. A subsequent dispute over his 10% commission, which the Beatles refused to pay during their 1961 Hamburg residency, ended the professional relationship. Williams let a legal claim for 104 pounds lapse by December 1961.
When Brian Epstein asked Williams about the Beatles in December 1961, Williams warned him: "Brian, don't touch them with a fucking bargepole." Epstein disregarded the advice and became the band's second manager.
Williams published a memoir titled The Man Who Gave the Beatles Away in 1975. John Lennon endorsed the book. The title was also later used for a musical by Irish playwright Ronan Wilmot, performed at the New Theatre in Dublin in 2002.
On the 9th of May 2016, Williams was made a Citizen of Honour of the City of Liverpool at a ceremony in Liverpool Town Hall. The award recognised his services to the local music scene.
The Jacaranda was a coffee bar Williams opened in 1958 at 21-23 Slater Street in Liverpool, converted from a former watch-repair shop. Its proximity to Liverpool Art College made it a gathering place for art students including Stuart Sutcliffe, John Lennon, Paul McCartney, and George Harrison, and it became the environment through which Williams first encountered the future Beatles.
