Folkscene used to be archived online, and I agree it was a wonderful show, with lots of live concerts. They were having financial problems and I don't know if it's still available.

We ain't got no folk music on the radio here in Honolulu, either. Well, that's not true, we have lots of Hawaiian music, including some traditional stuff that would qualify as folk music in my book. Otherwise, except for the Putumayo World Music Hour and Thistle & Shamrock on public radio, nada. It's too bad...I, like Teresa, was introduced to folk music via radio. In my case it was WXPN in Philadelphia, around 1977 or so. (Well, reintroduced, actually. I grew up with traditional Yiddish music on the radio and record player, old folk songs as sung by Burl Ives and Mitch Miller's gang, and "Hootenanny" was one of my favorite TV shows as a kid.)
