Lloyd Walworth was only 30 years old when he decided to start a community choir in The Dalles. Four decades later, the Cascade Singers are still going strong and will celebrate with a “Forty Years of Happy Singing” concert Saturday, June 4, at 7 p.m. and Sunday, June 5, at 3 p.m. in the same venue as their very first show — St. Peter’s Landmark.
