UPDATED: It's been announced that the 77-year-old veteran broadcaster and generally living legend has had to pull out at the last minute due to ill health. 

In a statement, Wogan said: "The British public, as always, will dig deep in their pockets and purses to help the country's disadvantaged children, knowing that every penny will go to those who need it most. I'm going to miss our wonderful, inspiring evening together, but I'll be with you, watching, cheering and donating to a magnificent cause... The show will go on, bigger and better than ever, in the hands of my friends, Grimmy, Fearne, Rochelle and Tess."

A BBC spokesperson added: "We are so sorry that Terry won't be with us tomorrow night as we know how passionate he is about Children in Need. But we wish him a very speedy recovery and know he'll be watching from home and enjoying the show."

While Wogan's replacement is yet to be announced (whileTess Daly seems to be the natural replacement, there are rumblings that either Matt Baker or the perennially present Chris Evans will step into his shoes), it has been confirmed that tonight's guests include The cast of EastEnders, who will be perform a musical number alongside Peter Andre. It's worth tuning in for that alone...

Meanwhile, Scott Mills will be live in Blackpool preparing to abseil down the 400ft Blackpool Tower. There will also be a Strictly Come Dancing special which will see the legendary Bruce Forsyth return to host, while Rod Stewart and Ellie Goulding will also be in for live performances, there will be a Star Wars special with Lord Alan Sugarand Jess Glynne performs the official Children in Need song, Take Me Home.
