Ireland, World War One. Dashing Harry Heegan leads his football team to victory, arriving home in swaggering celebration before he grabs his kit and heads for the trenches. A nightmare world awaits, the men, reduced to cannon fodder, speaking in mangled incantations as the casualties stack up. Months later, Harry returns, a cripple at the football club party. Everyone but the shattered war veterans dance and forget.Peppered with acrid wit and dark vaudeville humour, The Silver Tassie, Sean O'Casey's powerful anti-war play of 1928, receives a major revival at the National Theatre in April 2014.
