Thanks to the musical pride of La Crosse, Wisc. and its tendency to overshare, we've learned a lot about both show choir and Midwestern values days before the official Off Pitch premiere. Members of the Grand River Singers have a systematic approach to fishing for live bait as well as female affection, but when it comes to a big gig, how do they prepare?
