Yup, that's the sad downside of an otherwise very humane and warm-hearted author, Larry, and I can understand if you revised your opinion of him.I used to be a regular listener at Johnnie Keenan's "Pavee club" session in Slattery's of Capel Street, Dublin in the early 70s, and remember hanging out with Paddy at a Listowel Fleadh around that time. Maybe we've met without knowing it. I got my first practice set from John.
Manitas, you might be right, though the person who wrote the Danny Boy words may never have seen pipes of either kind in the flesh!
