Da is as old as the hills. His son Thomas, a mere stripling at close to 100. They are Ireland's past, its history and its traditions. They are also a dead end with no foreseeable future - until Thomas admits to a one-night stand almost 70 years ago. Soon Da and Thomas are tramping over the boggy Irish countryside in search of the absent son.
At times, Mark Doherty's play seems to fall victim to the very ideas and stereotypes it sends up. It is bogged down in a literary tradition that owes much to Yeats, Beckett and Flan O'Brien, but has the wit to keep its head above the brackish water.
There is even a tongue-in-cheek fiddle accompaniment, and lovely surreal touches such as the great olive crisis and the oxygen ban of 1916 when nobody was allowed to breathe on weekdays. It is impossible not to enjoy a play with such a sense of humour.
