These materials document the Irish music career of Boston-area accordionist Joe Derrane. The 1940s recordings that brought him recognition are included, as is his copy of a phonograph featuring his mentor Jerry O'Brien. His late-career return to performance is documented by his diatonic button accordion, the second made for him by the French craftsman Bertrand Gaillard, a modified version of the maker's Cristal model. The accordion case also contained one of Derrane's set lists. Further materials include a program and a photograph from his receipt of a National Endowment for the Arts National Heritage Fellowship, and photographs of him with his Gaillard accordion.
