This is a sequel to Costello's 2010 track "Jimmie Standing in the Rain
," which tells the story of a vaudeville performer in the '30s who has fallen on hard times. In "Under Lime," it's 20 years later and he is attempting a comeback, but having a rough go of it. He agrees to appear as the "mystery guest" on a TV quiz show, where a young, female production assistant does her best to dodge his advances and get him to the stage. Once on the show, he make a fool of himself, setting back his career even further.
