Yes. The song had definitely immigrated by 1858; I believe I got that date from a citation of sheet music. It was printed in America in that year.

Now, what I have not gotten into is whether in that version he got off (A flaw was in my indictment found, and that soon had me free....) or whether he went to the gallows still smitten by the L/W. I would guess that the version where the Irish Civil Liberties Union lawyer gets him off on a technicality is later, but I do not know that part for a fact.

PS Sang it at a gig last night. Great melody.
