I'll bet a fiver that Sarah Millican
will make a guest appearance during the first series.
You're 100% correct Audio Rebel!
(although there are certain male comedians who are also on every show). Also, they are also going to be having Josh Groban and Alice Cooper as guests! Here's a list of 17 guests. I don't know how many episodes this series will be.
I'm curious to know who was on the episodes that people in this thread saw.
