On today's edition of Dakota Midday, host Paul Guggenheimer welcomed Black Hills artist Jon Crane and Forest Service Archeologist Tony King to the program for a discussion of how to preserve the past in the Black Hills and prevent overdevelopment. Then, Paul interviewed Grammy Award winning blues guitarist John Hammond who is performing at the Orpheum Theatre in Sioux Falls on Saturday. Hammond has more than 30 albums to his credit and has collaborated with Muddy Waters, Bob Dylan, Eric Clapton, Bob Dylan and Tom Waits. Paul even broke out his Tom Waits impersonation for Hammond.
