Ted Powell — entering his 25th year as organist of the Yankton United Church of Christ-Congregational — will use the Yankton College Memorial Pipe Organ to accompany the swashbuckling silent movie classic, “The Mark of Zorro,” starring Douglas Fairbanks, in the church’s historic sanctuary (5th & Walnut) on Saturday, October 21, at 7:30 p.m. This free event is the second in a new series of Dakota Prairie Concerts; freewill offerings will be accepted. The next four free events will be held in February, March, and April 2024.
