Was your landlord aware that there's a theory this gig caused his pub to appear in Don McLean's "American Pie"?
When the Jester sang for the King and Queen
In a coat he borrowed from James Dean
Maybe it's nonsense but I saw this online at http://www.levitt.co.uk/v3.html (and the article mentions other theories involving JFK & Jackie, and Martin Luther King and Joan Baez):
"The Jester is Bob Dylan as will become clearer later in the song. In 1962 Dylan went to England to star in a BBC programme as a rebel of some sort. During his visit, he sang in a few clubs, these were his first gigs in the UK. On the 23rd December of that year he performed at "The King & Queen" pub in 1 Foley Street, London. So Dylan literally "Sang for the King & Queen"."
