I have a close friend here who plays "trad" more than anything else.
Years ago he made the journey to the mother isle to study at the source.
He planned to spend a month in the pubs playing Irish music.
He said it took a few nights to get to know the locals, but at some point it all came together and they let him play along.
Before it was over the locals expressed an enthusiasm to learn the songs my friend brought over which he thought of as Traditional Irish music and the Irish locals started teaching my friend their favorite songs which they thought of as new world Appalachian folk.
Funny stories that all seemed to end up with music being played down on the beach as the sun came up.
Good times.
