Diarmuid and Grania is a play in poetic prose co-written by George Moore and W. B. Yeats in 1901, with incidental music by the English composer Edward Elgar.
George Moore wrote a novel based on a translation by Lady Gregory of the Fenian tale The Pursuit of Diarmuid and Gráinne.
The play, in three acts, was dedicated to Henry Wood, and its first performance was by Frank Benson's English Shakespearean Company at the Gaiety Theatre, Dublin on 21 October 1901; it appeared in a double bill, being followed by Douglas Hyde's Casadh an tSugáin (The Twisting of the Hay Rope) performed by Irish-speaking amateurs supplied by the Gaelic League (the first Irish-language play ever seen on a regular stage).
Although the collaboration had been difficult – Yeats and Moore disagreed frequently, mainly about style, and there was therefore no final version for publication – the production was well received.
[3] The Funeral March received its first separate performance in the Queen's Hall, London on 18 January 1902, conducted by Henry Wood.
