Edward Petherbridge is a most accomplished and diverting actor who probably first came to the notice of Irish audiences with his marvellously dry performance of Newman Noggs in the Royal Shakespeare Company's television production of Nicholas Nickleby. This week he is in the infinitely smaller RSC production of Beckett's elegy to isolation and wilfully lost youth. His Krapp starts out more comical than most others: banging about looking for his tape recordings and recorder, digging out his bananas from the locked drawers of his bare desk.

His voice is lightly Dublin-accented but, unlike most Irish interpreters of the role, this is a brusque old man who does not roll the words around in his mouth: here is something of an unkempt Stan Laurel (the vaudevillian echoes are excellent) who keeps dropping things and whose mind seems more on the mechanics of how to play his old tapes than on the lingering images which those tapes should conjure in his mind. The brief references to his mother's death behind a blinded window scarcely register at all emotionally, and his recall of seduction lacks erotic resonance.

But this is still an original and entertaining interpretation of Beckett's lonely old man, either unmoved or irritated by his youthful record. It is directed by the actor and David Hunt, more or less within the author's stringent instructions and stage directions. Its brief 50 minutes is followed by discussion between actor and audience.
