The Vermillion Community Theater production of “The Sound of Music” is certainly a family affair. All but one of the young actors portraying the von Trapp children have parents involved in the production. Incoming VHS freshman Issac Mayrose, who is playing the eldest von Trapp son, is appearing alongside his father, Bryce, who has a supporting role. The elder Mayrose says, “It’s a lot of fun to spend time with him in an activity that we both enjoy and that we both have fun with.”
