"When Irish Eyes Are Smiling" is a lighthearted song in tribute to Ireland. Its lyrics were written by Chauncey Olcott and George Graff, Jr., set to music composed by Ernest Ball, for Olcott's production of The Isle O' Dreams, and Olcott sang the song in the show. It was first published in 1912, at a time when songs in tribute to a romanticized Ireland were very numerous and popular both in Britain and the United States. During the First World War the famous tenor John McCormack recorded the song.
