Three Dog Night - One

Three Dog Night is an American rock band formed in 1967, founded by vocalists Chuck Negron, Cory Wells, and Danny Hutton. This lineup was soon augmented by Jimmy Greenspoon (keyboards), Joe Schermie (bass), Michael Allsup (guitar), and Floyd Sneed (drums). The band had 21 Billboard Top 40 hits between 1969 and 1975, with three hitting number one. Three Dog Night recorded many songs written by outside songwriters, and they helped to introduce mainstream audiences to writers such as Harry Nilsson ("One"), Randy Newman ("Mama Told Me Not to Come"), Paul Williams ("An Old Fashioned Love Song"), Laura Nyro ("Eli's Comin'") and Hoyt Axton ("Joy to the World", "Never Been to Spain").
The phrase "three-dog night" refers to a night so bitterly cold that one would need three dogs in bed to stay warm.

Lyrics:
[Verse 1]
One is the loneliest number that you'll ever do
Two can be as bad as one
It's the loneliest number since the number one

[Verse 2]
"No" is the saddest experience you'll ever know
Yes, it's the saddest experience you'll ever know
'Cause one is the loneliest number that you'll ever do
One is the loneliest number, whoa-oh, worse than two

[Bridge]
It's just no good anymore since you went away
Now I spend my time just making rhymes of yesterday

[Chorus]
One is the loneliest number
One is the loneliest number
One is the loneliest number that you'll ever do
One is the loneliest
One is the loneliest
One is the loneliest number that you'll ever do

[Bridge]
It's just no good anymore since you went away

[Outro]
(Number)
One is the loneliest (number)
One is the loneliest (number)
One is the loneliest number that you'll ever do (number)
One is the loneliest (number)
One is the loneliest (number)
One is the loneliest number that you'll ever do (number)
One (one is the loneliest number that you'll ever do)(number)
One is the loneliest number that you'll ever do (number)
One is the loneliest number that you'll ever do
