Every once in a while I stumble upon a heartwarming story about a teacher that just warms my heart. Here is one about Robert Moore, a retired high school music teacher from Ponca City, Oklahoma.

Robert’s 30 year career as an educator began in 1966 and ended when he retired in 1996. He just celebrated his 80th birthday, so as a special surprise, nearly 300 of his former students decided to pay homage to their former music teacher. In an effort that took nearly a year to organize, they traveled from all over the country and from three foreign countries back to their home town of Ponca City. There they rehearsed and performed a surprise tribute concert for Robert. Some of the selections they performed brought Robert to tears, such as “Kumbaya” and the Christmas song “Still, Still, Still.”

Many of the former students described their teacher as a strict disciplinarian who pushed them to perform beyond what they thought they had in themselves. “He expected the best out of us, and therefore we gave the best that we had,” remembered Katy Cutler-Art, class of 1975. “He would stop you in the hall and ask you to sing a specific note,” recalled Susan Clay Vitkavage, class of 1979. Because of Robert’s expert guidance, the Ponca City Chorale won choir competitions all over the country every year that he served as their director. Many of the former students said they pursued successful careers in music or became educators because of the inspiration they gained from Robert.

Despite his rather tough teaching style, Robert obviously still harbors great affection for his former students. “Thank you so much for this,” he told them at the conclusion of the concert. “You’ll never know what it means to me and to my family. I loved you then, and I love you now.”
