The BBC also released the first two minutes (after the opening titles) of part two. Additionally, the 2009 Christmas idents for BBC One featured David Tennant as the Doctor using the TARDIS as a sleigh pulled by reindeer. Though unrelated to the episode, it was used to introduce both parts of the story, with Tennant himself providing a voiceover introduction for Part Two. After Part Two was broadcast, the ident continued for the remainder of the day but no longer featured Tennant, since he was no longer the Doctor. Concurrently with the recording of the story, a music video was produced, featuring the cast, extras, crew and CGI Adipose, all lip-synching and dancing to the Proclaimers' 1988 song, "I'm Gonna Be (500 Miles)". Tennant appeared with each pair of featured actors, as well as with the Proclaimers themselves. Overnight ratings placed Part One as the third most watched programme of Christmas Day, behind "EastEnders" and "The Royle Family" with a provisional viewing figure of 10.0 million viewers. The episode achieved a 42.2% share of the total viewing audience, and an appreciation index score of 87, considered 'Excellent'. Final consolidated ratings placed Part One as the third most watched program of Christmas Day, behind "The Royle Family" and "EastEnders" with a final figure of 11.57 million viewers. This is the highest timeshift that the show has received since its revival (the previous highest being 11.4 million for "The Next Doctor" in Christmas 2008). When simulcast HD figures are added to the BBC One transmission, "Doctor Who" actually comes out as the most watched show on Christmas Day with a total of 12.04 million viewers, narrowly ahead of "The Royle Family" and "EastEnders". Overnight ratings placed Part Two as the second most watched programme of New Year's Day, behind "EastEnders", with a provisional viewing figure of 10.4 million viewers (including 389,000 watching on BBC HD). The episode achieved a 35.5% share of the total viewing audience on an evening where an estimated 30 million viewers were watching TV in the UK. Official BARB ratings placed Part Two as the second most watched programme of the week behind "EastEnders" at 11.79 million viewers; however, when the simulcast figures on BBC HD are added, an additional 480,000 viewers bring the total figure to 12.27 million. When this figure is recognised, the program becomes the most watched of the week, only the third time the show has achieved this.
