Surely it's worth reminding ourselves that these are recordings of people who chose to sing in public at a folk club? Seems weird to suggest that anyone happy to make their music public (to a room full of people) would have a big objection to making their music public (via the internet).

YouTube is full of iPhone-captured footage of gigs, buskers etc. I think anyone under 30 would find the qualms expressed in this thread completely mystifying.
