The tune is from the Hebrides Islands, off the north cost of Scotland. An alternate title Lewis Bridal Song refers to the Isle of Lewis, which may be its origin.
This is a lament written in the late 1700's for the closing of the Whisky distilleries in Scotland. It may also be played as a slow air. The forbidding of distilling whisky was due to a national grain shortage at the time, but the ban was subsequently lifted. Whisky was required for births, weddings and funerals so Scots often buried stores for forthcoming ceremonies. There is a story in Glenlyon of a man who emigrated, forgetting his whisky. He wrote back saying where it was buried but they never found it, or so they claimed.
This is a polka or morris dance tune from England. The girl may refer to a ship's figurehead and blue dress to the sea. There is a sea shanty with the same name, but different tune. However, the phrase "girl with a blue dress on" is also documented in an African-American muledriver's song, and the meaning is not certain.
