Stevie Wonder made magic Sunday night at Target Center in downtown Minneapolis. The 74-year-old Motown legend — and, let’s face it, true national treasure — offered a memorable evening of classic songs, humor and abundant joy. It was one of 11 pre-Election Day concerts on an outing he’s calling “Sing Your Song! As We Fix Our Nation’s Broken Heart” with the stated goal of calling for “joy over anger, kindness over recrimination, peace over war.”
