I loved skiffle too: used to listen to "Saturday Skiffle Club" on my tranny before it became "Saturday Club". Had a big crush on Lonnie when I was a teenager.
The last time I saw him, he was doing a headline concert at Sidmouth Folk Week in the outdoor arena at The Knowle: he had already had his heart bypass surgery by then, and put on a tremendous performance.
Oh, and I do have a washboard - metal one side, glass the other. Cost me all of £5 in a junk shop in Innerleithen: the thimbles cost me more!
