I found the Notting Hillbillies concert from Birmingham (1998, night 5 from 6) on YouTube. I never saw MK talking, smiling, laughing so much, I think especially on "Rope Stretching". I enjoyed it very much. Unfortunately, I understand not so much of their talk on stage. So I don't really know why they are laughing. That's really too bad. Nevertheless, it was and it is a pleasure to watch this video.
Thanks for uploading.
