One of the Beeb's better ideas for a "reality" show,
Well, technically, not quite: there was a previous series: Green Valley with the same people on C4 (although I believe that C4 is sort of owned by the BBC so, technically, technically, you are really correct) that did a c15 or c16 farm in Wales.
But yes, it's a great series.
And I now have a claim to fame having spent a few weeks digging, camping and drinking with Alex and Fonzie (Peter) a while back.
