Keep A-Knockin' (But You Can't Come In)

...
Keep a-knockin' but you can't come in
Keep a-knockin' but you can't come in
Keep a-knockin' but you can't come in
Come back tomorrow night, try again

I hear you knockin' but you can't come in
I know you've been drinkin' gin
Ou've been cheatin' 'round with other men
I'm busy and you can't come in
