Yes, very sad news. Sorry Sandy was in such poor health for so long before passing on, too.
Like Jennie, I never had the privilege of meeting Sandy or Caroline, but it's clear thier contributions to the folk community, as musicians, folk historians, and just plain menchen, have been tremendous.   Wish I could have met Sandy in person. So glad he's left so rich a trove of recorded music behind.

My condolences to Caroline and the rest of the family.
