By the 1920s, melodeons and accordions had become well established in Irish traditional music, especially in Irish America where they were popular band instruments. Agents for Globe accordions in particular were successfully targeting Irish players in the United States by the mid-1920s with a variety of amateur and professional instruments, and using the prominent Cork-Boston accordion player Jerry O’Brien in advertising campaigns. At the end of the decade New York resident James C. Morrison of Riverstown, Co Sligo, well known in the city on stage, record and radio, was commissioned to write a tutor for the Globe accordion. ‘Professor’ Morrison (1893–1947) was primarily famous as a fiddle player, but he also sold, played and taught the accordion, among other instruments. He included in the tutor a selection of tunes suitable for beginners, reproduced on the left, from the popular contemporary repertory, most of which had been published on Irish commercial recordings in New York.
