Lyrics:

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
One...........

One is the loneliest number
