The new Rainy Lake Square was packed Thursday evening for beloved children’s entertainer Fred Penner. Fans of all ages filled the square with lawn chairs and balloons to enjoy old classics and new tunes, such as “The Cat Came Back,” “Sandwhiches,” and “I Hear the Music.” After the show, many stayed to wait in line for a moment with Penner for autographs and pictures, or just to chat.
