[1] The Log Driver's Waltz directed by John Weldon set to the recording of the song by Kate & Anna McGarrigle with, and as part of, The Mountain City Four is one of the most-requested items contained in the collection by the National Film Board of Canada.
When Secretary of State for Canada John Roberts announced in the fall of 1977 that $13 million would be given to federal cultural agencies to help promote national unity, the NFB was allocated $2 million to produce films for broadcast on the CBC, similar to CBS's Bicentennial Minutes in the United States, the previous year.
Many of the films were animation vignettes offering amusing portrayals of Canadian history, while others were produced from excerpts of NFB documentaries.
[1] The CBC's children's department subsequently informed the NFB that it could not show films longer than two minutes as their needs had changed in the time that it took to produce the series.
The series was also sold to international foreign broadcasters in such countries as Turkey, Italy, Algeria, Norway and the United Kingdom.
