We're thrilled that our tour has us heading west to Mitchell, South Dakota this weekend, for a show at the Corn Palace, which, yes, is a palace made of corn. (Yes. Seriously.) We invited some of our best friends to join us: fiddler Johnny Niemann, sultry singer Prudence Johnson, sound-effects guy Fred Newman. And we'll also welcome acoustic duo The Ditty Bops, as well as former South Dakota senator George McGovern. (Yes. Seriously.)
