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
You've been cheatin' around with other men
I'm busy and you can't come in
