The hills surrounding Moffat County High School soon will be alive with melodies from the great-grandchildren of Captain and Maria von Trapp, the family whose story was featured in "The Sound of Music."
The children, 16-year-old Sophia, 14-year-old Melanie, 13-year-old Amanda and 10-year-old Justin will perform nearly 40 years after the movie portrayal of the Hitler-defying widower and father of seven singing children.
The von Trapp children are performing at 3 p.m. Sunday in the Moffat County High School auditorium.
The children have continued the tradition, singing and sharing family stories of life before and after coming to America. They live in the mountains of Montana and are home-schooled by their mother.
They have appeared on "Good Morning America" and at the Grand Ole Opry, and they performed in Seoul, South Korea, and Sydney, Australia.
They sing familiar songs, including a number or two from "The Sound of Music," accompanied by piano and accordion.
The von Trapp children wear lederhosen and dirndl skirts as they perform favorites from the 1965 movie, including "Edelweiss" and "Do-Re-Mi."
The performances are family affairs, the von Trapp heirs said.
Sophia is in charge of organizing the shows, and Justin not only likes Lederhosen -- "They're really comfortable, like overalls," he said -- he also enjoys working with his sisters.
"The best part is, I get to annoy them, day and night." Justin said.
