"Jack Was Every Inch A Sailor" is a traditional Newfoundland and Labrador folk song. It is a comical retelling of the Jonah tale, with a Newfoundland whaler as protagonist, but in this instance the whale gets his comeuppance.
It may have been adapted from a New York City music-hall song "Every Inch a Sailor", which itself was a burlesque of "HMS Pinafore".
This song was covered by Canadian children's singing group Sharon, Lois and Bram on The Elephant Show.
