I live in the lovely Monadnock region in southwestern New Hampshire, USA. Bob MacQuillen is a local contra dance musician who has played for over 50 years. He was directly involved in the contra dance revival with Ralph Page and the rest of them. He lives in Peterborough, is in his 70s at least, and is feisty, funny, and a lovely man. He will be honored at the Ralph Page weekend in January (I'll look up a URL when I have time) and has recently had a video done about him.
I believe Amelia's Waltz is his one "hit" but there may be others.
My favorite memory of him is when my morris team went to dance at his house right after he came home from the hospital after heart surgery. He met us at the door, wielding a real-live-here-now blunderbuss and cussing at us-"Git off my land, you $#*!!" with such a twinkle in his eye!
