I see she's published two Junior Cert Irish-language textbooks* (if it's the same Máire ní Chéilleachair) so I suppose if anyone would know, she would! Incidentally, the friend of mine who sings this (a fluent Irish-speaker from west Cork) is a great fan of Máire's. I won't be seeing her for awhile because she's away home, but will ask and report back if she can tell me anything. Thanks!
