The movie was shot in 1968, and was kindly supplied by Roger Månsson and Roger Berg of Sweden, who were part of the student tour group in the movie.

The soundtrack has some extracts from interviews with former Leak staff. The detailed sequence of staff in the soundtrack is shown in the credits at the end of the movie.

The first person you will hear is Phil Biggs, Leak’s Factory Manager — and one of the long standing employees from the early 1940’s through to 1969. Then Ted Ashley, Chief Engineer at Leak is heard. Without Ted’s input, the book “Firsts In High Fidelity” would not exist.
