1. The band:
* Three Dog Night is the name of a popular American rock band, formed in 1967 in Los Angeles, California. They were known for their strong vocal harmonies and their covers of songs by other artists.
* Their name is a reference to a term used by Australian Aboriginals to describe a particularly cold night, so cold that you'd need three dogs to keep warm.
* The band achieved massive success in the late 1960s and early 1970s with hits like "Joy to the World", "Mama Told Me (Not to Come)", "Black and White", "One", and "Shambala".
2. A weather phenomenon:
* Three Dog Night is a slang term used to describe a very cold night, particularly in the northern United States and Canada.
* The term is often used humorously, with people saying things like "It's so cold out, I need three dogs to stay warm!"
* It's not a recognized weather phenomenon with a specific temperature range or definition.
So, when you hear "Three Dog Night", it could refer to the band or a very cold night. The context will usually make it clear which meaning is intended.
