I've found all the other "You Picked a Fine Time to Leave me Lucille" parody except the one I am looking for. The first couple of lines are,

"At a bar in the Gorbals,
Just doon frae the orange halls,
At a bar room he lay on the flair."

and the chorus goes,

"You picked a fine time to leave me Yvonne,
With the rent over drew and the bank over drawn.
I filled you with Buckfast,
How long would our love last..."

and now i cant even remember the chorus!!

If anyone can help me please post ASAP!!
