It begins with a tall, thin man walking out of light and into darkness. There is much that remains murky in Barry McGovern’s adaptation of this novel by Samuel Beckett, written between 1941 and 1945 when Beckett, who had worked for the Resistance, was in the South of France on the run from the Nazis, and not published until nearly a decade after its completion.

Samuel Beckett recalled sinking into a "whirl of depression" while writing All That Fall. Audiences at this production - those, that is, who have managed to score a ticket for this short, sold-out run - are unlikely to emerge into Jermyn Street in a similarly gloomy frame of mind.

When I lived in the Caribbean in my twenties, one of the books I found at the bottom of the remaindered bin of Kingston’s largest book shop was Theatre of the Absurd by Martin Esslin. I read it without any real sense of its context but there was something about its central idea that struck a chord with me. Perhaps it was living in a society where death and violence were part of everyday life, perhaps it was my own rather bumbling efforts at understanding existentialism that made it remarkable. Esslin talked a great deal about Waiting for Godot.  

So this is Christmas, a time to seek comfort in traditional nourishment both culinary and cultural. In Edinburgh, the King’s Theatre has been home to mainstream panto - the equivalent of serving up a hearty turkey with all the trimmings – since time immemorial, which leaves the capital’s other theatres jockeying for position. What to do? Hedge all bets and aim for different-but-not-too-different, or raise the stakes and try something more adventurous altogether?

There’s always the risk, when you put a tape machine in front of Michael Gambon (b. 1940), that it won’t be recording the truth and nothing but. His taste for mischief-making is legendary, his low boredom threshold a matter of fact. It doesn’t take a shrink to come up with an explanation. Film parts may take come thick and fast these days, not least in the interminable Harry Potter franchise, but Gambon loves a live audience.

A play could be written about, or for, Michael Gambon's fingers, and perhaps Beckett's 1958 Krapp's Last Tape is it. I've seen this solo piece many times, most recently in a studio theatre rendition from Harold Pinter that opened a window on to his own mortality and won't quickly be forgotten. But what Gambon brings to the table - well, desk - is the abiding sense of a man struggling for his share of the light amidst darkness at the very moment that his powers may be slipping away.

The wait is over. Less than six months after dramatic literature's defining tramps departed the West End, here are Vladimir (Didi) and Estragon (Gogo) back again, with some new faces to flesh out Beckett's eternal verities about that grievous but also grimly funny thing we call life. Roger Rees has joined Ian McKellen to make up a double-act whose vaudevillian tendencies intensify the more these two abject fellas face down the void.

Beckett is less forbidding now than he might have seemed when he was alive, and certainly when his work was first performed. Over the last two decades, crueller and darker plays than his have been written, though none have matched his lyric ingenuity and his pained, sometimes devastating irony remains unsurpassed. Can Endgame, the bleak successor to Waiting for Godot and perhaps the oddest dramatic masterpiece of the 20th century, still hurt us? And what, I feel it legitimate to ask, might lie behind a desire to revive it in the West End?
