One is the loneliest number that you'll ever do
Two can be as bad as one
It's the lonliest number since the number o-o-one

No is the saddest experience you'll ever know
Yes it's the saddest experience you'll ever know
Oh-oh-oh
'Cause, one is the loneliest number that you'll ever do
One is the loneliest number, when you're lost at two

It's just no good anymore 
Since you went away-ay-ay
Now I spend my time 
Makin' rhymes of yesterday

One is the lonliest number
O-one is the lonliest number
One is the lonliest number that you'll ever do
Woh-one is the lonliest
Woh-one is the lonliest
One is the lonliest number that you'll ever do

It's just no good anymore 
Since you went away-ay-ay

Number one is the lonliest
Number one is the lonliest
Number one is the lonliest number that you'll ever do
Number one is the lonliest
Number one is the lonliest
Number one is the lonliest number that you'll ever do
