The two I went to see - class and language - were a bit weird. Some funny stuff, but Henning doesn't seem a particularly comfortable interviewer, especially with the guy brought into talk about class, who was funny in a way but didn't really seem to understand how a conversation worked.
And Otto, the guy who played music, was amusing up to a point, but his 'stings' just seemed to be random, and often came in the middle of two connected gags.
All just seemed a little loose and under-rehearsed.
