This sounds like a great combination. Nancy-Jean Seigel, Helen Hartness Flanders' granddaughter, has been doing a wonderful job of exploring the Flanders recordings and raising people's awareness of what a treasure house they are. And I agree with Ron that Debra Cowan has a special quality of respecting and caring about each song she sings. Sounds as if it's a very special combination.
Hooray that there's a release party/concert scheduled for the DC area. We are in a craft show that weekend but if we aren't totally exhausted on the 17th we will be at that concert.
