Big Time: I dont know if the Clancy Bros did Arthur McBride...I'd be surprised if they didnt know a song as widespread as that.But I would guess Bob Dylan would have heard Arthur McBride sung by Redd Sullivan or Martin Carthy in 1962 in London, even if the Clancys werent doing it in New York. Dylan was in maximum listening mode on that visit...witness Nottamun Town, the Patriot Game and Franklin! I'm just proposing he heard Arthur McBride as well.
