Joining David this week are Olympic cyclist Sir Chris Hoy and impressionist Ronni Ancona. Teaming up with Lee are comedian and author Danny Wallace and sports presenter Gabby Logan.

Did NASA really ask Chris to be the first man to cycle on the Moon? Does Gabby really post birthday cards to her pets? And is a performance by Shirley Bassey the only concert that David has ever been to?
