You can listen to Part 1 via the BBC iPlayer for the next four weeks. Part 2 airs at 18:30 GMT tomorrow, 24-Dec-2014, on Radio 4.
Possibly you already knew that. :)
If you don't live in GMT, use the time zone map to find the time proper for you.
After the live broadcasts on Radio 4 and Radio 4 Extra, which are open worldwide [huzzah, dear Beeb!] you can always use BBC iPlayer.
Strewth! I was very grateful, since I am NOT in the UK area whatsoever.

FYI: John Finnemore says to avoid news outlets, as they are flinging around Zurich spoilers. His blog post is amidst the Farewell Bear Facts, which will avoid Zurich for a few days, but Part 1 and Part 2 do have blog posts for comments.
If you must discuss Zurich, please do it on his blog. You can't spoil the folks [one hopes!] who are commenting.
Do be considerate of your fellow fans, I pray you -- not everyone heard Part 1 today, nor will they, either live or on iPlayer. So if you use quotes or spoilers, PLEASE mark them appropriately, wherever you are online.
Also, the lovely fellow fans at Cabin Pressure Fans have some advice for how to listen to the eps.
My apologies for not posting sooner. [Had medical issues over the weekend, which are resolving -- yay!] I hope you can get the chance to enjoy John's blog posts and Zurich too. If not, give yourself the holiday present, eh?
