I'm not sure of the name of this song. Grandpa Jones recorded it. the chorus goes,

It's raining, raining, raining here this morning
As I'm sitting here a-waiting for my bride.
I'm watching how the river is a-rising
As the ran keeps on a-falling from the sky
If I started counting teardrops falling one by one'
I would have a million before the day is done
It's raining, raining, raining here this morning
And I wish I was back behind those prison bars
