I'm fortunate in Chicago to still hear Rich Warren on Sat nites.   Also, for great, long-running great shows, try the KPFK shows - Wildwood Flower, Hearfelt Music, and the grand-daddy Folk Scene - Ros is planning to start posting the current week's interview on folkscene.com - this week is Ellis Paul - don't everyone try at once, we don't want to put too much stress on the site. Ros and Howard Larman do an excellent job of keeping the music going.
