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
"No" is the saddest experience
you'll ever know
Yes, it's the saddest experience
you'll ever know
Because one is the loneliest number
that you'll ever do
One is the loneliest number
that you'll ever know

It's just no good anymore
since you went away
Now I spend my time
just making rhymes of yesterday (one by one by one)
Because one is the loneliest number
that you'll ever do
One is the loneliest number
that you'll ever know
One is the loneliest number
One is the loneliest number
One is the loneliest number
That you'll ever do
One is the lonelist number
much, much worse than two
One is a number divided by two

(Life isn't easy when two are divided
And one has decided to bring down the curtain
And one thing's for certain
There's nothing to keep them together)
