Christopher Plummer, who was a concert standard pianist with a fine musical ear, was furious when his singing voice was dubbed in “The Sound Of Music” (1965), and went on a drunken rampage through Salzburg. (He told me in an interview that the dubbing incident was one of the reasons he was rude about the film.) This is Plummer’s original vocal performance of “Edelweiss” - a chance to hear the song as he recorded it.
