This is a perfect example of a song I was embarrassed to like back when it was a big hit but that I'm not the slightest bit embarrassed by today. If you Google "embarrass," the first thing that comes up is Embarrass, Minnesota. I guess I like that.
I don't have much to say about Three Dog Night. Their name is a reference to sleeping with dogs to keep warm. The colder it is, the more dogs you need, so a really cold night is a three dog night, like maybe lots of nights in Embarrass, Minnesota, which I see calls itself "The Cold Spot," and highlights the record low temperatures (-57!).
You could make other band names using the Three Dog Night format -- just an idea for the comments. You know, like: Two Coffee Morning or Ten Blogpost Day. I never bought an album by Three Dog Night. In fact, this single was probably my brother's. Anyway, "One" was written by Harry Nilsson.
One is the loneliest number that you'll ever doAnd I do have an album by Harry Nilsson, the one most people who have one Harry Nilsson album have: "Nilsson Schmilsson." ("She put the lime in the coconut....")
Two can be as bad as one
It's the loneliest number since the number one
UPDATE: Don't confuse this "One" with other "Ones." There's:
Darkness imprisoning me
All that I see
I cannot live
I cannot die
Trapped in myself
Body my holding cell
That's not Harry's song. He also didn't write:
When it's one need
In the night
It's one love
But the song Aimee Mann sings on the "Magnolia" soundtrack: that is the right "One."
