I have played dozens of IPs, but I don't really know Skarpi. There is just one observation, which I would like to offer. When a group of Irish guys (and gals) gets together, they sing. They don't give a bugger's about "what is folk?" or any of that stuff. They simply sing the songs they know and like. Some of the songs are undoubtedly folk songs by any definition, others are not. I have often wondered whether that might not be the reason why traditional music is probably better preserved in Ireland than it is in most other countries.
