David Letterman American talk show host (born April 12th, 1947) got drunk here for a week

When Ricky Gervais appeared on the Letterman Show in 2011 he had a commemorative blue plaque installed outside the London pub that David used to go to. The plaque is no longer there. see http://www.lateshowuk.com/shows/late-show/8369/lettermans-birthday-gift-from-ricky-gervais
