[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

[Refrain]
Because one is the loneliest number that you'll ever do
One is the loneliest number that you'll ever know

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

[Refrain]
Because one is the loneliest number that you'll ever do
One is the loneliest number that you'll ever know

[Outro]
One is the loneliest number
One is the loneliest number
One is the loneliest number that you'll ever do
One is the loneliest number, much, much worse than two
One is a number divided by two
One
One is the loneliest number
