This week's show is now available via the BBC iPlayer. Please visit the link any time between now and the start of the next programme.

I woke up this morning (not an intro into a blues song) and it dawned on me that this week's show would be my last live Sunday night show on BBC Radio Wales after 10 years of diligently playing (frequently) un-Christian sounds on Sunday nights.

From 7 January 2012 I will be in a new sonic foxhole on BBC Radio Wales: Saturday nights, 10pm-1am.

I thought the best way to kiss goodbye to Sunday nights would be to treat you to an early Christmas present of many of the best pieces of music that have passed through my radio window since November 2001. So, you get rarely heard session tracks; some favourite album tracks and rare demo recordings of some of Wales' most excellent leftfield to gloriously accessible musicians of the new millennium.

The playlist is detailed below. But anything that encompasses Mclusky, Murry the Hump, Gruff Rhys, Ten Thousand Yen and many others has to have something going for it, other than its presenter's raging ego.

We're also joined by Alun from Y Niwl discussing the brilliant wave of psychedelic surf sounds on the new vinyl pressing of their eponymous debut album. That album won them a Sunday Times Album of the Week back in January. They've toured the world in the last 12 months as Gruff Rhys' house band. And Football Focus chose their track Undegpedwar as its new theme tune. All of which gives us quite a bit to talk about...

Alan Holmes reminds us of Brenda Prescott and the Warm Richards (that's the polite, BBC Wales music blog-friendly version of their name.)

Fresh from a significant birthday (with a '4' in it), Ben Hayes gets as festive as he's ever likely to get with a rather unfestive piece of The Goons.

Lara Catrin's translates one of Wales' great Christmas songs.

And there is great music. Not a definitive list of the Greatest Welsh Songs of the last 10 years, but definitely some of my favourites. I hope you enjoy it. It'd make a strange soundtrack to your office Christmas party but should serve you well in the midst of a sherry frenzy - or in the painful clutch of the ensuing hangover.

On Christmas night at 10pm I'll be broadcasting my Best of 2011 - the pieces of music of Welsh origin that moved me and excited me most over the last year.

On New Year's Day at 10pm I'll be talking to Gruff Rhys about his life making music - and particularly about the incredible, award winning year that has just passed for him; we'll have a Georgia Ruth live set recorded a few weeks ago in Betws Y Coed, and Llwybr Llaethog have crafted something amazing in low, low bass for us.

Happy Christmas/Nadolig Llawen, and a genuine thank you/diolch yn fawr to anyone who has listened to, or contributed music to, the show.
