I don't get into singarounds and folk clubs much these days but when I do I'm usually very surprised at the diversity. There are far more unexpected/new-to-me songs than those you expect to hear. I suppose this is healthy. And I suppose I'm lucky because I can even join in with gusto with Black Velvet Band and Wild Rover, oh yes and even Fields of Athenry, without cringing.
Welcome the new and savour the old!
