I thought JK looked a bit bemused by it all! I presume he did a bit of merch after the gig ("Come and buy my latest Edison cylinder waxing")

Another Harvest Home with folkies performing is the one in the film of "Far From the Madding Crowd", featuring The Great Swarbrick. Resembled the folk scene of 30-40 years ago as the yokels were all drinking brandy, thanks to naughty Sergeant Troy. The scene where the hung over men (including the vicar) crawl out of the barn is priceless - reminded me of a few parties in the Notting Hill area.
