This week on A Prairie Home Companion, we've stumbled into grace with very special guest, Emmylou Harris and her notorious Nashville band. Also with us, live from the Fitzgerald Theater, bluesman Spider John Koerner, The Royal Academy of Radio Acting: Tim Russell, Sue Scott, and Tom Keith, The Guy's All-Star Shoe Band with sole man Pat Donohue, and our happy host, an escapee from the silent generation, Garrison Keillor.
