Del Boy, Rodney and Albert arrive at Drury Lane London thinking they are delivering dodgy goods to Chunky Lewis, a nightclub owner in the West End. Unfortunately they take a wrong turn and end up walking into the middle of the Royal Variety Performance. They mistake the Duchess of York for Chunky... bear in mind she was not too slim in those days.
