This group is one that always brings back hilarious memories of my younger brother and I belting out these songs on long car trips.And yes, the UP is part of Michigan (sadly), but I can vouch for the fact that Yoopers sometimes migrate, and can occasionally be spotted as far south as south-central WI. (Ahh, a Christmas miracle, being towed out of a ditch in a snowstorm by people with the accent from God's Country.)Great music, but not everyone will appreciate it. Their loss.
