Midnight Star will open with music from their platinum-selling albums “No Parking on the Dance Floor” and “Planetary Invasion.” Then, fairgoers are in for a treat when the No. 1 R&B group of all time, Boyz II Men, performs songs from the albums that have earned them Grammy’s for best vocal group and best album. The group will croon out crowd-pleasers such as “On Bended Knee,” “It’s So Hard to Say Goodbye to Yesterday” and “I’ll Make Love to You.” When fairgoers leave this concert, they will know that Boyz II Men has certainly not reached the end of the road.
