From Byter Charlie Z:
Are you sure “three dog night” didn't come from Alaska? Alaskan sled dogs share tents with their masters, and I can't picture aboriginals sharing space with 3 dingoes!
Charlie is referring to the post on the origin of band names.
The following sentence is from the Three Dog Night (band) website at:http://www.threedognight.com/band.html
The now-famous name came from a story about Australian aborigines who, on cold nights in the outback, sleep with their dogs for warmth. The coldest evenings are known as "three dog nights".
That explains the band name but is Charlie right, that the term more likely applies to sled dogs?
