One
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

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 loneliest number, much, much worse than two
One is the number divided by two
