Studio 360's series American Icons continues with a look at Woody Guthrie's "This Land is Your Land." Kurt Andersen speaks with Pete Seeger and others about how the song found its place in American culture. Later in the hour, Kurt talks with sci-fi writer William Gibson, who chose not to set his new book Zero History in the future – the here-and-now is freakish enough. And we'll hear from the multi-lingual, musically-gifted comedian Reggie Watts.
