"Talcahuano Girls", also known as "We'll Rant and We'll Roar" is a British sailing song about the early 19th century Pacific sperm and right whale fishing. It is the south Pacific version of the song "Spanish Ladies".
This song comes from the South-Sea whalers who, particularly during the first half of the 19th century, sailed out of London and Hull to hunt sperm and right whales off the coasts of Chile and Peru. Talcahuano lies south of Valparaiso in Chile; Huasco is about midway between Valparaiso and Antofagasta.
It was recorded by A.L. Lloyd on Leviathan! Ballads & Songs of the Whaling Trade (1967) and Danny Spooner and Duncan Brown on The Great Leviathan (2006).
