This weekend, the BBC held one of its Doctor Who Proms, a concert in which an orchestra performs musical selections from the television show. Matt Smith and Jenna-Louise Coleman were on hand an in character to appreciate the music.
It's a rather cute segment, especially when Clara notices the Doctor is missing a good bit of his hair. But we also get some great spectacle when Strax and the Cybermen show up for the musical accompaniment to the "I am the Doctor" speech.
