Pooling together a dozen or so key names from music, comedy and literature, the Save The Children Christmas Tree Sessions will take place on Friday 14th December at the Union Chapel and will include some top names - two of which have just been announced.

None other than Elbow's Guy Garvey and fundraising regular and TV personality Mylene Klass have been added to the bill - as a duo! Klass has 'previous' as a performer, firstly in pop group Hear'say and secondly as an acclaimed classical pianist. Garvey is renowned for his work as a broadcaster as well as Elbow's husky raconteur and songwriter. To spice things up, the duo are asking YOU what they should sing and perform for you on the night (head to Twitter and follow the hashtag #XMASTREESESSIONS). We imagine 50,000 have already tweeted 'One Day Like This'.

Leading the rest of the music bill will be Spiritualized, followed by Band of Skulls, Guillemots frontman Fyfe Dangerfield, Summer Camp, Kodaline and Josh Kumra. Comedy and spoken-word is represented by the well-wicked Lee Nelson, The Thick of It star Chris Addison and BBC 6Music presenter and author of the excellent Cider With Roadies and Pies and Prejudice: In Search of the North, Stuart Maconie.

We still have tickets for the show, which starts at 7pm and ends at 10.30pm, priced at £40.

Plus, there's a dress code - Christmas jumpers and/or Festive attire are a must. We can't guarantee the merchandise stall will be selling any, but you never know. 14th December is designated, Christmas Jumper Day and you can follow the hashtag #xmasjumperday for further details - there will be no escape from nightmare knitware and wayward woollens.
