A few extra warm-ups in London would have sharpened up proceedings. That way, we'd get a little less reliance on audience targeting - a subdued set of punters are hardly going to bite if the put-downs come too quickly - and a bit more originality in the gag department (heard the one about not being able to tell the difference between Camilla's wedding and the same day's Grand National? We have, but Hill tells it again anyway).
