I would also recommend A Song For Ireland, written by Mary O'Hra, published by Michael Joseph, copyright date 1982, ISDBN 0 7181 2161 9.

Song lyrics, beautiful photographs, and bits of narrative about the songs and her performing them. There was a 'companion album and cassette on Valentine Records LP VAL 8053 and VL 68053".

My copy is a library discard and cost all of 60p ($1).
