The Sound of Music

The heart-warming musical, The Sound of Music, was released in 1965 and went on to become one of the most successful films of all time. It was based on the true story of the von Trapp family singers. But was their life really as it was portrayed in the movie? Maria von Trapp's youngest child, Johannes, talks to Louise Hidalgo. The programme was first broadcast in 2015.
