Sir Tom will be celebrating his amazing career by performing some of his greatest hits and collaborating with artists including James Morrison, Laura Mvula, Chickenshed, and The Shires.
Comedy contributions come from David Walliams and Jessica Hynes, and there's even a themed mini-episode of The Trip with Rob Brydon and Steve Coogan.
It's all in aid of Children in Need before the big night of fundraising tomorrow.
