The Pennywhistlers

I've been thinking a lot more about Pete Seeger ever since I went to see The Power of Song when it was playing here in New York. I had known about his albums and concerts, but not about his TV shows. Which, not surprisingly are available on Youtube. Here's one with Johnny Cash and June Carter (not yet Cash herself...). Cash appears to be pretty strung out here, but the singing is still impressive.
And this is a group called the Pennywhistlers who I'd never heard of but apparently made a name for themselves with Eastern European folk songs.
