    The Headliner, holding the copy in hand,
        Read with a solemn face:
    "The music was very uncommonly grand --
            The best that was every provided,
            For our townsman Brown presided
        At the organ with skill and grace."
    The Headliner discontinued to read,
        And, spread the paper down
    On the desk, he dashed in at the top of the screed:
        "Great playing by President Brown."
