Doctor Who: Mutter's Spiral Podcast

It's the long-awaited (by whom, exactly?) return of Mutter's Spiral Podcast.  John and Will are back after a LONG break, and they're talking about the 2012 Christmas episode, "The Snowmen".  What did they think of the ep?  How are they finding Jenna-Louise Coleman as the new companion(s)?  Is there anything more awesome than Vastra, Jenny & Strax?  Can Will answer some trivia questions correctly? All that and more, including lots of Series 7b news!  Take a listen!
