Knockin' On Your Screen Door Letra

I could use some help here with a can of pork and beans

I once had a family but they up and left me
With nothing but an 8-track, another side of George Jones
I was in high cotton, just a-bangin' on my six-string
A-kickin' at the trash can, walkin' skin and bone

I can see your back porch if I close my eyes now
I can hear the train tracks through the laundry on the line
I'm thinking it's your business, but you don't got to answer
I'm knocking on your screen door in the summertime

Everybody's out there climbin' on the trees now
Swingin' in the breeze now, hangin' on the vine
I'm dreamin' 'bout a sailboat, I don't need a fur coat
Underneath the dashboard got some sweet potato wine

I can see your back porch if I close my eyes now
I can hear the train tracks through the laundry on the line
I'm thinking it's your business, but you don't got to answer
I'm knocking on your screen door in the summertime
I'm knocking on your screen door in the summertime
