Jerry is an accomplished Irish American musician. As a youngster he learned Scottish highland bagpipes, then took up the uilleann pipes following a visit to his cousins in Dublin. He became a member of Green Fields of America in the 1980s, rubbing shoulders with Seamus Egan, Eileen Ivers and Mick Moloney.
He has appeared on over 90 albums. Some of the more notable are "Heartsongs" (1994 - Dolly Parton) and "Bones" (1996 - Susan McKeown). Jerry's presence was rather more obvious on two albums by Eileen Ivers - "Wild Blue" (1996) and "Crossing the Bridge" (1999). He has recorded three solo albums, "The Invasion" in 1987, "The Gift" in 1998, and "O'Sullivan Meets O'Farrel" in 2005.
