OKOBOJI — Can it be fall already? Autumn is quickly approaching and Spirit of Harmony Chorus of Spirit Lake is preparing for their fall show, “Let’s Sing Again,” at 1 p.m., Saturday, Oct. 1, in the Lauridsen Theatre at the Pearson Lakes Art Center in Okoboji. Their last show was in the fall of 2019. The chorus is excited to share their music with their fans after such a long hiatus.
