Alternative title: the Derek Jacobi show. There are other good points to Thea Sharrock's production of John Mortimer's autobiographical play, transferred from the Donmar.

But they are sporadic, while so dominating is Jacobi's performance as the blind, bullying, barrister father at the play's centre that you miss him too much when he's off-stage.

Mortimer builds the story of his life under the paternal influence and his education and career at the Bar through a series of linked character sketches. With the exception of Christopher Benjamin's prep-school head, the comic cameos are safely amusing rather than powerfully funny.

The only developed character besides the father is the narrator son, and Dominic Rowan puts little vim into the author's already modest self-portrayal. It's scarcely credible when he steals Natasha Little's feisty married mother Elizabeth. When she says he is growing like his exuberant dad, it sounds wishful thinking.

Yet Jacobi is superb, and an almost constant presence. Revelling in his character's curmudgeon wit, he remains a life force, his belligerence fuelled by a peculiar joyfulness.

He's wonderful to watch and the death scene, beautifully underwritten and underplayed, will only fail to choke the soulless.
