Like many a regular theatregoer, I have a little list of classic plays that I’ve never seen, or even read. One of these is, or rather was, Errol John’s evocatively titled Moon on a Rainbow Shawl. Written in 1953, this definitive “yard play” was a historic breakthrough for Caribbean playwrights in Britain. So it was with considerable anticipation that I went to this revival, which opened last night at Britain’s national flagship venue. But can this classic stand up to scrutiny?

Was it the players, or the play, that has made a phenomenon out of One Man, Two Guvnors, the prize-winning comedy now on its third London theatre and preparing to hop the pond to Broadway next month? Well, bacon and eggs(!), it turns out there’s life aplenty in Richard Bean’s Goldoni rewrite yet, even without the star wattage of James Corden and the insanely arched eyebrows of Oliver Chris.

Polymath Philip Ridley is British theatre’s prince of imaginative writing. At the moment, he’s clearly on a roll, and this year his diary has been filing up fast. First, there was a majestic revival of his 1991 debut, The Pitchfork Disney, with a cast led by Chris New and the Channel 4 Misfits star Nathan Stewart-Jarrett, then there’s an upcoming London fringe revival of his 2005 shock-fest Mercury Fur and a national tour of Tender Napalm, his 2011 Southwark Playhouse hit, in May and June.

“Do you feel morally superior to the Taliban? Well, do you?” And we’re off, with another of director/choreographer Lloyd Newson’s interrogations of a taboo subject. DV8 Physical Theatre is 25 years old this season, yet if anything, it, and Newson, have become more challenging, not less as the years go by. Gone are the lyrically silent pieces of the 1980s, and instead movement is almost always now allied with talking; indeed, talking has become Newson’s main mode of communication, as his urgent need to vanquish our beliefs and replace them with his becomes ever stronger.

Mike Leigh’s Abigail’s Party: comedy classic or Who’s Afraid of Virginia Woolf? with added sneering? Ever since its first appearance on stage in 1977 and its subsequent record-breaking broadcast as a BBC Play for Today with an eye-widening 16 million viewers (not to mention those watching the subsequent DVD), there has been disagreement. Depending on your viewpoint, Lindsay Posner’s competent new production lives either up or down to your expectations.

Harley Granville Barker is hardly a household name, but he was a huge influence on British theatre today. During the Edwardian era, he promoted new writing at the Royal Court; he wrote plays such as The Voysey Inheritance, Waste and The Madras House, which have been successfully revived; he invented the modern idea of the director; he advocated permanent companies of actors; and he campaigned for a national theatre. Not a bad legacy. Now he is the subject of a new play, which opened last night, by American penman Richard Nelson.

Since their launch just two years ago, National Theatre Wales has staged plays on a firing range, in a miner’s institute, and – most memorably – claimed the whole town of Port Talbot as their stage for Owen Sheer’s The Passion last Easter. Setting themselves the challenge of producing 12 productions in their first 12 months, this building-less company have somehow turned a modest (not to say meagre) £1 million a year subsidy into a living, risk-taking tradition of national theatre.

What is it about the Sixties that keeps drawing us back? Surely, it can’t just be that anniversary thing – 50 years on? Perhaps, in these care-worn times, we just like to revisit our don’t-give-a-damn  anti-heroes, having their cake and eating it, pleasuring their mates’ marriage-weary wives, arranging abortions if things go wrong, downing pints in the pub. That was the life.

“The lady from the sea” is what a remote Norwegian fjord town calls the young second wife of its good doctor, an elusive woman who seems to walk in the footsteps of the ghost of her well-loved predecessor. Joely Richardson is doing much the same by taking on an Ibsen role previously frequented by her mother and sister, Vanessa Redgrave and Natasha Richardson, and directed by her dad, Tony Richardson - and it’s hard to say whether it’s her comparative slightness of gifts or Stephen Unwin’s domesticated direction that make so little of an enticingly strange play.

What’s it like to be young, British and Muslim in the age of austerity? In an era of global financial crisis, high unemployment and shrinking pay packets, what can this country offer British Asian youth? New talent Ishy Din poses these questions in his storming debut play which takes a trip to the local snooker hall in the company of four blokes, plays a few rounds of pool, downs a few pints and then chats its way up and down the walls and across the ceiling of the place, before quietly staggering home.
