The original issue of "Kate Kearney" seems to be a single sheet song with music issued with imprint 'Sold at M. Kelly's Opera Salon Pall Mall', 'Sung by Mr. Incledon The words by Miss Owenson'. This was stamped on, so Kelly probably had contacted out the music engraving and printing. [Copy of that and Kelly's issue of "The Boys of Kilkenny" (on my website) at the Folger Shakespeare Library] Kelly also had a wine shop adjacent, both being near the King's Theater, where he was acting manager.
