...and here it is. Just broke my record, less than 10 mins!
Based of coyrse on the Everly Brothers hit

I'll never let you see
The way my coughing lungs are hurting me
I got my pride and I know how to hide
Every nicotine stain
I do my smoking in the rain

Slip out in stormy skies
Then smoke and cough till I get tears in my eyes
Where I have been looks like a disaster scene
Just cigarette butts remain
I do my smoking in the rain

I love you more than heaven
But our relationship is never enough
So when we are together
I pray for stormy weather
I hide the packet and go out for a puff.

Someday when my coughing is done
I'll wear a minty smile and walk in the sun.
I may be a fool
but till the end darling you
Never see me complain
I do my smoking in the rain.
