After a quarter of a century as Principal Conductor of the RTÉ Concert Orchestra, Proinnsías Ó Duinn was appointed their Conductor Laureate in 2005. The same year he was invited by The Royal Dublin Society to conduct the “Irish Ring” (Maritana, The Bohemian Girl and The Lily of Killarney). For the occasion he was commissioned by them to make a new edition of the full score and orchestral material of The Lily of Killarney from manuscripts found in The British Library. In 1989 he was also appointed Music Director of Our Lady’s Choral Society, a position he still holds. Since 2001 he has been conducting the Birthday Celebration performance of Handel’s Messiah in Halle, and in 2011 he was invited to conduct the first of a series of concerts to include the complete symphonies of Haydn with the Orchestra of St Cecilia.
