House parties do happen, but I guess a carpark party would need a Licence from the Local Authority now in the UK-- or at least that's what some jobsworth would claim... following this with interest, because imho the traditional venue for our kind of music is being snuffed out by legislation and, dare I say it, sometimes our lack of appreciation of the costs of running a pub. Personally, as I can't drink much beer, I think it reasonable to pay £1 for a glass of coke if I'm getting a heated room, an environment in which to play and a friendly atmosphere. It's the price of admission. Again imho sessions are where the hearty music lives- the friendship & unity- and folk/acoustic clubs have really to take place in separate rooms, purely because of the need for quiet among the audience if attenders are paying to get in. And yes, both are dying because of the killing of the pub trade. Enjoy while they last.
