If you were the only girl (in the world)

I would say such wonderful things to you
and there would be such wonderful things to do

if you were the only girl in the world
and I were the only, I were the only boy
nothing else would matter in the world today
we could go on loving in the same old way
a garden of Eden just made for two
with nothing to marr our joy

then I would say such wonderful things to you
there would be such wonderful things to do
if you were the only girl in the world
and I were the only boy
