There's nothing like a University audience to energize our old radio show, so this week we're headed to West Lafayette, Ind., to broadcast from the campus of Purdue University, close by the Wabash in famed Hoosier land. Our special guests include the "Jimi Hendrix of Bluegrass" Jerry Douglas and his band, senior savant of the diatonic harmonica Howard Levy, singer Prudence Johnson, and the Purdue University Varsity Glee Club. Also featuring the Guy's All-Star Shoe Band, the Royal Academy of Radio Acting, and the News from Lake Wobegon, all this week on A Prairie Home Companion.
