There are of course still many excellent folk clubs about. However the days have passed when there was one, and often more, in every town which regularly booked professional guests. The majority of clubs these days seem to fall mainly into the singaround category, or book a guest only occasionally. On the whole I don't believe these are proving all that successful in attracting younger audiences, although again of course there will be exceptions.

A house concert is, unsurprisingly, a concert in a house. This does limit the size of audience, but many conventional folk clubs draw no larger audiences. They tend to be publicised on social media, which might exclude older audiences. However this isn't much different from the pre-internet days when often the only way to find out about events was by word-of-mouth.

Dick, I don't know who you've confused me with but I haven't mentioned Paddy Butcher. I always post under my own name.
