This gets curiouser and curiouser. "Dawning of the Day" was one of O'Lochlainn's all-time favourite songs. He sang it in public at a concert in Dublin in 1913 (no further details to hand). He was born in Dublin in 1892 and died in 1972. He wasn't a native Irish speaker, though he learned to speak it like a native and was quite scathing about other "big" collectors, notably Bunting, Petrie, and Joyce, for their almost complete ignorance of the Irish language, as he saw it. He hated Bunting in particular, calling him "arrogant".

Spanish Civil War? No!                                 

O'Lochlainn might change an odd word here or there, perhaps to |"improve" the rhythm, but he had too much inegrity to change the meaning of a song.

btw, his name wasn't "Colm"!
