From BBC.com: It's not long now until Friday night - and Time Crash, the special Doctor Who scene starring David Tennant and Peter Davison.
As well as Time Crash, written by Steven Moffat and directed by Graeme Harper, the Children In Need telethon will also feature the vocal talents of John Barrowman, who will be singing during the evening.
In association with Children In Need, the Doctor Who website team will be doing our bit to support this historic meeting of two Doctors.
If you're in the UK, you'll be able to catch the scene online for seven days after it's shown on TV, along with a very special behind-the-scenes featurette from the Doctor Who Confidential team.
We'll also be running a mini episode guide, including galleries, a fact file and full credits.
In return, we really hope you'll appreciate all the hard work everyone on Doctor Who has given for free to make Time Crash happen, and donate generously to help those less fortunate than many of us.
