A slight correction, though it doesn't materially affect Callie's request.

I though I'd just confirm what I said using the Bodleian Collection. From this, it appears that Comin' Thro' The Rye, unlike Annie Laurie was fairly popular during the first half of the 19th Century. I still think that the modern versions will almost invariably spring from the "Jenny Lind" sheet music, which was incredibly widespread.
