I've never seen this snippet before, only the full Christmas Invasion episode, and I was really missing something great. As much as I enjoyed the 9th Doctor and my introduction to Doctor Who, the 10th Doctor is just fantastic from the get go. I envy those who were able to watch this special live, although it had to have been a bit jarring since the 9th Doctor only JUST started and got going before this regeneration. I'm so happy to have seen this, and I only wish that 9th and 10th could get together for an adventure someday. Maybe in audio format, who knows, right? Anyhow, words words words words... there.
