Most folk listen to the Tin Whistle and Fiddle (GRING) no matter what the rest are doing, except in rare cases where there is a good Piper, ohhhhh there are lots of student Pipers since it takes 14 years to get it half right. (Is that why they play half sets ? ..... )

There's a few records out that are great even if one does not play, Mary Bergin, Miko Russell - good starting place

Have fun
