I don't think I have ever seen such a rehearsed so called "chat show" - even the "surprised" couple brought up from the audience were very clearly in on the act. No wonder Prue Leith got slowly pissed - to cover the embarrassment I expect.

Would it be worth my while watching this on catch-up, as I missed it on the telly?
If you have nothing better to do yes, and two of the guests are Scottish. 
I thought most of it was pretty funny. I don't think anyone was supposed to believe the couple thing wasn't a set up, after the first few seconds.
Meh.
