The party continues with music from pop princess Pixie Lott, a rousing Children in Need performance from Justin Lee Collins and double-trouble from impressionists Jon Culshaw and Debra Stephenson. The king of the crooners, Harry Connick Jnr, sings live in the studio. There's an appearance from legendary detective Hercule Poirot, and tune in for a true classic from comeback sensations Spandau Ballet. With music marathons for this year's appeal taking place all over the UK, watch out for special performances from Paolo Nutini, David Gray and Annie Lennox.
