The mother of Seán Óg had a great and varied repertoire of songs. He studied singing with Mrs. Geraldine [Ghearóidín] Neeson; in Cork he studied music with Aloys Fleischmann; and appears to have been greatly influenced by Father Séamus Ó Floinn. The gClaisceadal in Dublin, had been previously directed, from 1927, by Fionán Mac Coluim, Colm Ó Lochlainn and Micheál Ó Siochrú. In 1949 Seán was invited to start the chorus up again [?]. He used to conduct the choral singing and teach the song repertoire. He was deemed the right person for this responsibility, not only because of his erudition and his abilities, but also because of his enthusiasm for songs from any and all areas of the Gaeltacht. 120 songs from the repertoire which he taught, were published in a series of a dozen booklets titled An Chóisir Cheoil. Consequently, a delegation of the Recital Committee towards Radio Éireann instituted "Claisceadal an Radio."
[Sorry this is clumsy. This is difficult to penetrate with the translate program!]
Sean was the director and this small group performed in Recitals By the Liffey for the next 11 years. He released a recorded album of their music.
