Keep A Knockin' (But You Can'T Come In)

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

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