Julie Delpy’s 2 Days in New York, released on DVD and Blu-ray today, is the fifth feature written (or co-written) and directed by the French actress-filmmaker and her sequel to 2007’s 2 Days in Paris. It is, therefore, another hyper, chaotic comedy of Franco-American cultural discord.

The past few years have seen the anniversary reissue, or concert tour in which classic albums are performed in their entirety, become something of a standard. Not so for Tori Amos, who this year is celebrating two decades since the US release of her debut solo album Little Earthquakes. To mark the occasion, she is instead collaborating with the Netherlands’ renowned Metropole Orchestra to rework and recreate some of her best-loved songs in an orchestral setting.

Michael Frayn (b 1933) has been having an annus mirabilis. The play the hapless actors of Noises Off are touring is called Nothing On. In the playwright’s case, almost everything has been on. Frayn’s best-known farce spent the first half of the year tickling ribs at the Old Vic and then in the West End. A season in Sheffield featuring his more serious plays furrowed brows while one of them - Democracy, his play about federal politics in 1970s West Germany – had a run down in London.

Rob Ashford occupies a unique perch in the Anglo-American theatre. Florida-born, raised in West Virginia and a product of Broadway, where he began as a dancer in shows including Parade, Victor/Victoria and the celebrated Lincoln Center revival of Anything Goes, he some while back crossed to the other side of the footlights to build a career as a director/choreographer that has spanned the Atlantic.

Lady Gaga arrives in the UK this weekend to play two huge shows at Twickenham Stadium, before moving on to Manchester. Today, she is the biggest pop star in the world. Three years ago she was in the final stages of a highly orchestrated campaign intended to claim that position. What follows is an interview with her in Israel in the autumn of 2009, right around the time the world went Gaga gaga.

Ian Hunter’s new album, When I’m President, is an almost obscenely vibrant piece of work for a man who – despite that impossibly golden mop of hair – is now 73 years old. But then Hunter has always been a rock'n'roll survivor. Born in Shropshire in 1939, he was a 30-something industry veteran by the time his band Mott The Hoople, four albums into a career that had failed to scale even the nursery slopes of fame and fortune, scored their breakthrough hit in 1972 with David Bowie’s glam anthem “All the Young Dudes”.

Pet Shop Boys are the kind of national treasure that make the English so inscrutable. For 30 years they have made pop music that is sophisticated, camp and deadpan, an unlikely formula which has shifted over 100 million records, making them the most successful pop duo ever. Their 11th studio album, Elysium, will be released on 10 September. Recorded in Los Angeles, it is a slower, more sumptuous work than their fans have become used to. Could it be the time has come for a change?

In February 2001 a brain aneurysm nearly killed Karl Wallinger. It didn’t do World Party many favours either. The aftermath of devastating illness resulted in a five year hiatus for his band, followed by a gradual, tentative return. Since 2006 there have been shows in Australia and America, but no new music and no gigs on this side of the pond. Until now.

Described variously in the press as "virile", an "Aryan hunk" and a "great blond bear" of a man, Stuart Skelton may be the physical embodiment of machismo, but there's nothing of the beefcake about his singing. A Heldentenor of rare beauty and lyricism, Skelton's rise to operatic fame may have come young, but his is a voice and a career that looks set to stay the course.

Marvin Hamlisch’s three Oscars all came in 1974. "I think now we can talk to each other as friends," he said as he accepted his third award of the night. He composed the winning song "The Way We Were" (and the film's score) for Barbara Streisand, having started out on Broadway as rehearsal pianist in Funny Girl. A wizened sage warned Hamlisch that it didn't do to win so much so young, but he paid no notice and a year later went and wrote the music for A Chorus Line, his Broadway debut.
