I heard it and coming on the heels of Ivan B's concert last night, it made me cry, too. They usually don't have the info from that day up until the next, so I wuld suspect tomorrow we could find a bit more info at NPR's site.It was beautiful. Wonder if Jean Ritchie knows it; she's on here now as kytrad, you might send her a PM, if she doen't see this thread by some chance.
