Will Young writes about going on Question Time for the Daily Telegraph. He's pretty honest:
There were also times when I thought I was out of my depth and I didn't really understand what they were talking about – but then I don't have a politician's level of artillery.
Honest, but also proving why he was a bad choice. If I want to hear a debate where participants "don't really understand" what's being discussed, I could tune in to Nicky Campbell's phone-in, couldn't I? Question Time is meant to be informed debate, surely?
