I caught this programme last night

I personally found it interesting although perhaps intense

The Housecarpenter was featured and its origins and was a song i learnt many years ago ~ I was struck by the variations of tunes used and guitar styles etc

Curt Cobain also was included there[I think] and the guitar "rifts" which were clearly copied, but then dunt we all!

Eliza Carthy singing Ten Thousand miles from Nick Jones too
**
Aside:
CBS recording of the same song bears a uncanny resemblance to NJ too
