Can’t wait for your appointment?

It might seem a bit strange to hear a commentary track before you have a chance to see the show, but BBC7 radio online is featuring David Tennant and Catherine Tate as they talk about the new season’s episodes of Doctor Who. The shows are live at 6:30 p.m. London time (1:30 p.m. EST, I believe), with reruns on the Listen Again feature for six days starting sometime Monday. They’re also running episodes of Paul McGann’s Doctor Who audio drama. The BBC radio sites block sports programs, but there’s no problem with the rest of the lineup.

The first episode has some good stuff, like Catherine Tate talking about how she felt about getting a regular gig and seeing her name on that “iconic credits sequence.” David Tennant drops hints about an end-of-season shocker that will be teased throughout the season (”Bad Wolf,” anyone). They tend to do specifics of the episode in a way that’ll leave you baffled and curious, instead of spoiling the surprise, so it’s more like a half-hour advert if you haven’t seen the episode yet. These two laugh a lot.

It’d be great if Sci-Fi Channel and CBC put these up on their sites after their runs, but that could be too much to hope for.

You can catch the Doctor Who commentaries at Listen Again under Sunday here.
