Going back some years, when we camped on MB, JK was performing at LM and the great man came for a wander round MB and sat and shared some beers with near-neighbours.
We only heard about it after the event, and I am not particularly knowledgeable about him or his music (except Virtual Insanity)
Just looked up - that'd be 2003 -
