That was really close, Tinker! The album is The Slightly Irreverent Mitchell Trio, and it indeed was the first album on which they dropped the "Chad" from their name. Yip Harburg's poem, entitled "For the Man of Extinction," goes as follows:

    Hammacher Schlemmer is selling a shelter,
          worthy of Kubla Khan's Xanadu dome;
    Plushy and swanky, with posh hanky panky
          that affluent Yankees can really call home.

    Hammacher Schlemmer is selling a shelter,
          a push-button palace, fluorescent repose;
    Electric devices for facing a crisis
          with frozen fruit ices and cinema shows.

    Hammacher Schlemmer is selling a shelter
          all chromium kitchens and rubber-tiled dorms;
    With waterproof portals to echo the chortles
          of weatherproof mortals in hydrogen storms.

    What a great come-to-glory emporium!
    To enjoy a deluxe moratorium,
    Where nuclear heat can beguile the elite
          in a creme-de-la-creme crematorium.
