Danny's link is about Question Time on TV, not Any Questions on Radio 4.
I thought the audience was lively in a good-natured way. They seemed a decent crowd: they tended to approve of the speakers who I thought were honest, well-informed ans spoke well. I don't think they expressed loud disapproval at the occasional daft statement by the Tory/Boris supporter. I do feel sorry for some of the c-listers who have to turn up for public humiliation now that the real baddies are kept off the media.
