“Christmas 1980": From the box text: “My fifth sound film was a pure casual work. On 23.12.1980 I was given two REVUE-films, which I shot during the Christmas preparations and the Christmas party. At the same time, a hidden cassette recorder recorded our very wrong singing. The film was edited on 26.1.1981 and set to music on 4.2.1981. It is 26 meters or 5:36 min long. Virgil Widrich, 6.2.1981"
