Actually, I did just get the link to work. It is the Co Tipperary Paddy's Internet collection, which sort of fell in the lap of a fellow by the name of Dave Gabol, who used to frequent the Irtrad mailing list. As I read through a few pages, I remember there was much discussion on the list. Dave Gabol hates concerntina w/piano accompaniment, as I recall.

So no, the Paddy O'Brien collection at Ceolas is not the NEA Paddy O'Brien collection, which was not transcribed by Co Offaly Paddy--he was very clear that he wanted recordings of the tunes made for those musicians who didn't read music, so they could learn the tunes by ear the way he did. He felt that was closer to the way the tunes were learned traditionally by Irish musicians, the vast majority of whom don't read music.
