The singer laments, "Must I go bound and you go free." (S)he hears someone sing "that marriage was a pleasant thing," but "My marriage day soon turned to woe." The singer's spouse has scorned/abused the singer; the singer hopes for revenge
This, like "My Blue-Eyed Boy," is so close to "The Butcher Boy" that I almost listed them as one song. But where "The Butcher Boy" is relatively coherent, this is little more than a lament composed of floating verses (e.g. from "Waly Waly") and the complaint "I heard (a shepherd//fair maid) sing That marriage was a pleasant thing, [but] My (marriage/wedding) day soon turned to woe." So I've listed them separately -- but there may well be intermediate versions.
