I admit that "better PR" is a bit glib. Of course there were Scottish bands, but I don't recall them making much impression on the part of the folk scene in southern England I was involved in at that time, certainly not to the extent of the Irish bands. I'd certainly heard of those bands, but I don't think I heard their music much. There just seemed to be a lot more Irish music around then, whereas I heard very little Scottish, and that of course influenced what was played in sessions.
