I made my admiration for the Copper family explicit a few posts back.

Like Brian, Cole praised Copper's book, so it's on my list, which is very long. In addition the Copper family have a web site offering a discography and a range of print-based products, including song-books. It 'links' section leads to various interviews and articles. They also have a facebook page. As I have said before, I don't see anything wrong with people embracing, to whatever extent, commercial possibilities for their work. If all this isn't promotional (and therefore potentially biased i.e. showing a preference one way or another) …

I like Joe's word 'showman' even though perhaps it isn't the word an English person would use in this context.

The last paragraph in my post on 1.17 am (as recorded here) was a general one, not one aimed at the Copper family. And I think it is a point worth making in general.
