Méav, and Hayley sing "The Last Rose of Summer" at the Slane Castle, Ireland. The Last Rose of Summer is a poem by Irish poet Thomas Moore, who was a friend of Byron and Shelley. Moore wrote it in 1805 while at Jenkinstown Park in County Kilkenny, Ireland. Sir John Stevenson set the poem to its widely known melody, and this was published in a collection of Moore's work called Irish Melodies (1807–34). In Ireland, it is claimed that the melody was composed by George Alexander Osborne.
