My uncle (Matt Scally of Ballycastle, Co Antrim, Ireland) made some recordings of Irish songs many years ago. One of them, 'The Old Lammas Fair', was in a BBC LP vinyl record of songs of the British Isles and is easily found. He apparently made other recordings, including 'Eileen Og' and 'Come back Paddy Reilly to Ballyjamesduff' that came out on 78rpm records. I've used Discogs to find vinyl but I can't find ways of searching for 78s. Does anyone have any advice?
