If people are really keen to see it outside the UK they've already released the DVD; I'm sure you could get it on Amazon if you've a player that supports whatever format it is we have over here.

I'd also like to point out that this is the second such series. The same three experts plus two others took part in the recreation of a Jacobean farm about five years ago. It was called 'Tales from the Green Valley'. No John Kirkpatrick, obviously, but they did get a chap in to sing songs and play instruments of the time. This is available on DVD also.
