years In 1963 Ó Riada was appointed lecturer in music at University College, Cork. He moved to Baile Bhúirne, and not Cúil Aodha (a common misconception) in West Cork, an Irish-speaking area, where he established Cór Chúil Aodha, a male voice choir. He turned toward choral church music, composing two settings of the Mass. Ceol an Aifrinn ("Music of the Mass") was the first Mass written in the Irish language. This featured the hymn "Ag Críost an Síol", which has become popular in its own right, and with such good phrasing, that it is (wrongly) thought by many today to be an ancient medieval tune. Aifreann 2 ("Mass 2") premiered posthumously in 1979. Further works in the "classical" tradition include Five Epigrams from the Greek Anthology (1958) and In memoriam Aloys G. Fleischmann (1964) to words by Hölderlin. Ó Riada also set the poetry of Thomas Kinsella (Three Poems, 1954), who returned the favour by praising Ó Riada in verse. He became involved in Irish politics and was a friend of several influential leaders. Ó Riada and his wife Ruth drank regularly at a local pub which still advertises itself as being his local. Death He suffered cirrhosis of the liver. He was flown to King's College Hospital, London, for treatment and died there. He is buried in St Gobnait's graveyard, Baile Bhuirne, County Cork. Willie Clancy played at his funeral. Legacy Seán Ó Riada and Ceoltóirí Chualann set to music the Peadar Ó Doirnín lyric Mná na hÉireann, which has been recorded or re-used by many artists. As performed by the Chieftains, it is used as a romantic overture throughout the Stanley Kubrick movie Barry Lyndon and is the basis of The Christians' 1989 single Words. Ó Riada's daughter Liadh Ní Riada was elected as Sinn Féin Member of the European Parliament in 2014. She was the Sinn Féin candidate in the 2018 presidential election. The Irish poet Séamus Heaney included the poem "In Memoriam Seán Ó Riada" in his 1979 collection Field Work. In 2008, a life-sized statue was erected in the grounds of Sépéil Naomh Gobnait, Cúil Aodha. On 23 April 2010 Ceoltóirí Chualann reformed under the leadership of Peadar Ó Riada to play a tribute concert to Seán Ó Riada in Dublin's Liberty Hall. In 2011, A festival, Féile na Laoch, was organised in his honour by his son, Peadar, between 30 September and 3 October
