The leaflet I picked up at Four Fools was for the inaugural event of the Yorkshire Traditional Song Weekends. It is taking place on 16-18th September at the social club in Drax, between Selby and Goole. The organisers are glad4trad based in Leeds. "Traditional singing sessions, featured guest singers..." including Brian Dawson, Ellen & Kevin Mitchell, Mary Smith, Grace Toland, John Waltham. I think they're hoping to keep it participatory (rather than concerts) so smallish in scale and manageable for a first event. Good luck to them. Tickets are £40 for the weekend but I don't know if there are any still available.
