This week on A Prairie Home Companion a special springtime poetry show with Allen Ginsberg reading the words of Walt Whitman, Meryl Streep reading the words of Wendell Berry and Mary Oliver, and Billy Collins and Rita Dove reading their own words. The poetic Randy Newman is on, along with Gillian Welch, Greg Brown and Bob Dorough. Plus, the story of another Bob: a younger, struggling artist with an iffy sense of meter and a tendency to slouch. Join us Saturday for all this and more on a special poetry home companion.
