True to form the Mariinsky Ballet has already made programme changes for its Covent Garden visit next summer, not a fortnight after announcing its tour on 3 December. But we're used to it and it's all to the good. Substituting Don Quixote for the Lavrovsky Romeo and Juliet originally planned means a more traditional cast to the tour, a much more sure-fire box office, and a direct comparison between the St Petersburg virtuosos and their Moscow rivals at the Bolshoi who for the past two years have made Don Q their party piece.

It has been around a few weeks but to mark the final weekend of X Factor with an estimated 20 million tuning in, it seemed apposite - so here's national treasure, polymath and humourist Stephen Fry on the delights of Wagner (below):

It’s the time of year when Tate Britain unveils its much-anticipated, artist-designed Christmas tree. Over the years, we’ve had Fiona Banner decorating hers with unpainted Airfix models of fighter planes, while Sarah Lucas hung hers with stuffed tights instead of baubles. Tacita Dean vied between tradition and Minimalism with a simple arrangement of beeswax candles, while both Mark Wallinger and Julian Opie decided to forego the fir tree altogether: Wallinger opted for a bare, spindly aspen decked with mass-produced Catholic rosary beads, while, true to his cartoon/Ikea aesthetic, Opie’s contribution was a fake forest of painted trees made of intersecting planes of wood.

Of the runners and riders for an alternative Christmas hit, Captain SKA's jolly tune with samples of Osborne, Cameron, Thatcher and Clegg is the latest one to be gathering momentum. The other campaign, already rolling on nicely and more likely to succeed, is the one to get Cage's silent "4'33" to Number One for Christmas - a rather brilliant protest and a perfect present for the conceptualists and anti-consumerists in your life.

Some rare restored film of pre-First World War Europe, shot by intrepid travelling cameramen from 1905 to 1926, is being shown tomorrow in an intriguing event at Europe House, the new home of the EU in London. Travelogues were a very popular early use of film, and cameramen competed to bring back the most spectacular footage or most exotic action from abroad, in order to have their film used on early cinema programmes which, before the age of feature films, were composed of several short films.

Dexter Dalwood appeared to be an early favourite, while many wished Angela de la Cruz, who had suffered a debilitating stroke five years ago, a deserved comeback triumph (though the artist who makes evocative “sculpture/paintings” of crumpled canvases did win the prestigious £35,000 Paul Hamlyn Award last month). Few, apart from this reviewer, appeared to be backing the Otolith Group. But in the end, it was 45-year-old Glaswegian artist Susan Philipsz, with recordings of three different versions of a traditional Scottish ballad, who bagged the Turner Prize last night.

We’ve got some CDs to give away, a recording of French horn music by Sarah Willis, the First Lady of the French Horn, who is also second horn in the Berlin Philharmonic. Our interview with Sarah in early September has proved to be one of the most popular pieces on theartsdesk.

It's been a while since the pop/punk and post/pre-Richey comparisons have been made. Ironic considering how seemlessly the Manics slip between modes these days. Today theartsdesk brings you an exclusive preview of the live, power-popping video of "Hazleton Avenue", due for release next Monday to coincide with their live digital EP, Some Kind of Nothingness (available on iTunes).

Christmas is coming, and prepare ye the way for a sledge-load of new music. It’s probably not just Stephen Cleobury’s annual commissioning of new carols for the King’s College Service of Nine Lessons and Carols that does it (though he must be partly responsible), but come Christmas every year there is a positive avalanche of new carols rumbling into the choral world. Whether broadcast to millions or sung to an audience of 37 in a tiny church carol service, Christmastide certainly gets the creative juices flowing among our composers.
