No, "Do bhí bean uasal" isn't published in Ó Muirthile, "An t-Amhrán Macarónach". Which leaves us back to questioning someone like Seán Ó Sé, Rachel Ní Riada, Peadar Ó Riada, Tomás Ó Canainn (he wrote a book about Sean Ó Riada) about the Irish language song.

OIn one of his books, piper (engineer, singer, poet, author) Tomás Ó Canainn mentions a 1790 publication of a tune called "Carrickfergus" but the air is that of "Haste to the Wedding", not the song we know of as Carrickfergus or Do bhí bean uasal.(see John Moulden's message on this aspect of the topic)
