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 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
I thought this was original with Little Richard, and then I thought "I Hear You Knockin" was original with Smiley Lewis. Shows how much I know!
