The world would be lost without raincoats

I swear your hair is such a perfect mess and confess it's a guess but you're broken hearted more or less.
Here you are without a car walking through the rain waxing public (something) in vain.
You wain, you wain, you wain, you wain.
(guy)9 times out of 10.
(girl)You'll come running back again.
(guy)6 times out of 8.
(girl)You tell yourself it's not too late.
(guy)3 times out of 4.
(girl)Keeping your eye on that front door.
(guy)1 time out of 2...
(together)I loves you. OOOOOOO. And the rainbows stop. OOOOOOO. And the rainbows stop...
(guy)The world would be lost without raincoats.
There, there. Don't dispair. There is plenty of fish in the sea.
One for you and two for me.
Let's go inside we'll make some tea.
