Lyrics:

You keep a-knockin', but you can't come in
You keep a-knockin', but you can't come in
You keep a-knockin', but you can't come in
Come back tomorrow night and try it again
You say you love me, but you can't come in
You say you love me, but you can't come in
You say you love me, but you can't come in
Come back tomorrow night and try it again
You say you love me, but you can't come in
You say you love me, but you can't come in
You say you love me, but you can't come in
Come back tomorrow night and try it again
You keep a-knockin', but you can't come in
You keep a-knockin', but you can't come in
You keep a-knockin', but you can't come in
Come back tomorrow night and try it again

spoken:
'Now on this next bit here I want everyone to sing along with me. It's very easy.
All the boys gotta sing 'You keep a-knockinand all the girls gotta sing
'But you can't come in'. You got that? Let's try it'.

You keep a-knockin', but you can't come in
You keep a-knockin', but you can't come in
You keep a-knockin', but you can't come in
Come back tomorrow night and try it again
