There's a great PhD to be written about why comics are so keen to dress as old biddies, from Arthur Lucan and Benny Hill to Dick Emery and Les Dawson, by way of any number of panto dames to the most noble of them all, Dame Edna Everage. To this esteemed list of comics should be added Brendan O'Carroll, whose Agnes Brown is an astonishing creation, a foul-mouthed Dublin widow whose passions in life are bingo and poking her nose into her children's lives.

Glenn Close always had it in her somehow. That mannish jawline was part of her steel cladding in Fatal Attraction. The lasting image of Dangerous Liaisons comes at the close, when Close’s Madame de Meurteuil scrapes off her painted mask to reveal a hard hatchet face. And then there’s her ruthless lawyer in Damages, not to mention two gruesome helpings of Cruella de Vil.

Popular operatic love stories by Puccini, Wagner and Mozart dominate the regional scene in 2012, but key talents like producer Tim Albery in Leeds, Lothar Koenigs in Cardiff and David McVicar in Glasgow all promise significant stage experiences.

Conor McPherson's 2000 play is one of the Irish writer's most memorable works, and this revival comes soon after his less acclaimed latest play, The Veil, over which we shall draw, er, a discreet veil, debuted at the National. It reminds us that McPherson at his best is a writer of humanity and compassion and, as a former toper who is now a non-drinker, one who understands the lure of the bottle.

“The whole world's in a terrible state of chassis,” says Captain Jack Boyle more than once during Sean O'Casey's great play, set in 1922 and the second of his Dublin trilogy, bookended by The Shadow of a Gunman (1923) and The Plough and the Stars (1926). It was first performed at the Abbey Theatre in Dublin in 1924, when Ireland - only recently free of the yoke of empire – was tearing itself apart over the 1921 Anglo-Irish Treaty, which established the 26-county Free State, later the Republic.

You’ve got to love the “I Can Only Give You Everything” riff. Admiral Black do and base their “Got Love if You Want It” around an inverted version on their debut album. Cheese-wire fuzz guitar pulses, Bo Diddley drums bash and a wheezy organ, well, wheezes. From the borrowed title alone, it’s obvious where Admiral Back are coming from: classic Sixties-leaning rock. It's not all scuzz and psych though in the house of Black. “Madman’s Blues” drifts by in a haze and “Crystallised” begs for lighters in the air and a swaying audience.

Mark O’Rowe is one of Ireland’s leading contemporary playwrights, and Terminus was first produced in 2007 by the Abbey Theatre in Dublin. It transferred to the Edinburgh Fringe in 2008 and is now being revived by the Abbey in an international tour. His play charts another ordinary night in Dublin city, but as this captivating triptych unfolds the events his characters - simply named A, B and C - describe are anything but. A man and two women deliver a series of overlapping monologues about love, sex, loss, regret and acts of shocking violence, but also of angels transporting souls to the afterlife, a demon made of worms and a pact made with the devil. The language - sparkling, funny and heightened - is poetic and fantastical, Molière meets magic realism.

“What’s the story?” It’s a question you’ll hear again and again in the streets and pubs of Dublin. You can tell a lot about a nation from their greeting; the traditional salutation of northern China, born of decades of famine and physical hardship, translates to “Have you eaten?”, and a psychologist could extrapolate much from our English fondness for impersonal, weather-related pleasantries. So it’s surely no coincidence then that Ireland, and Dublin in particular, should favour this conversational opener. A city home to some 50 publishing houses, that has produced four Nobel Laureates, arguably the greatest Modernist novel, and was recently named a UNESCO City of Literature: Scheherazade has nothing on Dublin.

Bob Geldof only shuts up in the end because a plane he should be on is imminently taking off for India, and he is still in his local South London pub, refusing to let a heavy cold stop him from talking like others drink - with unquenchable relish. He is in passing promoting his new album, How to Compose Popular Songs That Will Sell, a lesson Geldof could have given with conviction during his old band the Boomtown Rats’ pomp between 1977 and 1980, when their first nine singles hit the Top 20, climaxing with consecutive Number Ones “Rat Trap” and “I Don’t Like Mondays”. The way those achievements have been forever dwarfed by his marshalling of global compassion to save countless Ethiopians with Live Aid is something he can live with.

The Celtic Tiger ran rampant through Ireland during the boom years of 1995-2007 when national institutions expanded their collections, galleries popped up and collectors, buyers and artists had a rare time. With literature, the new young Chick Lit writers made their mark, sometimes even outselling the serious contemporaries, and Seamus Heaney rightly got a Nobel Prize. With the crash, prices in Dublin’s major art auction houses fell by 50 per cent as the blinged-up property developers froze; if they did buy, they shifted from contemporary to reassuringly Irish "genre paintings" of peasants in rural landscapes and thatched cottages by the sea.
