Hi Ian She was singing back up on an LP 'Sea Songs' sea festival series #2 in 1980 by the Sea Hertage Foundation, I also remeber doing Shanties on something else but can't remeber what. She's also on an LP called 'St. James Gate' put out by Kells Records in 1985, 35 Rodman St. Jamaica Plain, Mass. 02130, Tel # 617-524-2856 , I don't know if there still around, I called the # but got no answer. Good luck
