That scrambles footage from the BBC certainly brought back memories. It was probably as fuzzy on the old B&W sets then as it is now!
I met Jeff Smith once. He had his BSA (B40 based) bikes maintained (and was still riding them) by the late Fred Barlow who was my Norton Commando guru and had a little shop in Tamworth conveniently on the way when I had regular trips from Brum to York in the early 1990s Jeff was a very nice chap and very unassuming.
