I find the following two verses from a "ribald song" sung by a teamster in a wagon train on the California Trail, c.1949.  It is quoted in Forty-Niners by Archer Butler Hulbert (Little, Brown & Co., Boston, 1931), p. 25.  This is a real but composit "diary" of the way west.

    I never changed my fancy shirt,
      The one I wore away,
    Until it got so rotten
      I finally had to say:
    Farewell old standin' collar
      In all your pride o' starch,
    I've worn you from December
      To the Seventeenth o' March.

    No matter whether rich or poor,
      I'm happy as a clam;
    I wish my friends could look
      And see me as I am.
    With woolen shirt and rubber boots
      In sand up to me knees;
    And lice as big as Chili beans
      A-fightin' with the fleas.

That's all I have about the song.  Would any have any more info?
