This year's annual Children in Need telethon will begin tonight at 7pm on BBC One and various entertainers will be performing live on stage to help raise money for the charity. A special preview clip from this year's third special episode of Doctor Who will be shown and according the event's schedule, it will air sometime in between 8pm and 8:30pm. Once the clip has been published online, it will also be posted on this site so don't worry if you miss it when it's first shown. John Barrowman, who is well known for his role as Captain Jack Harkness in both Doctor Who and Torchwood, will be performing live at the event tonight and more information about this year's telethon can be found here where you can also find details about how you can help the charity.
