Bud Herseth, the legendary Chicago Symphony Orchestra trumpeter, died Saturday at 91. We revisit our 2004 conversation with Herseth -- as well as John Callaway's 1978 conversation with prima ballerina Maria Tallchief -- who died last week as well, on Chicago Tonight at 7:00 pm. Watch the full videos of Herseth and Tallchief from WTTW's archives by visiting the links below.
