A second, a minute, and hour, a day goes by.
I'm hopin' just to be by your side.
I'm turnin' the handle
It won't open.
Don't make me wait, cause right now I need your smile.

Knock Knock

F5             C5             A5           G5
When life had locked me out, I turned to you
So open the door.
F5                 C5                   G5
Cuz' you're all I need right now it's true.
G5                  F5
Nothin' works like you.
F5                             C5
Little louder, little louder, little louder, knockin'
A5                        G5
Little louder, little louder

(verso)
C5            C5           A5          G5
A warm bath, a good laugh, an old song that you know by heart.
C5            C5          A5       G5
I've tried it but they all leave me cold.
C5          C5            A5
So now I'm here waiting to see you,
G5         C5              C5          A5
My remedy for all that's been hurting me.

(refr?o)
D5       D5  F5
You seem to    know the way
   C5             G5
To turn my frown upside down
D5  D5   F5
You always know what to say
G5
To make me feel like everything's ok.

F5                             C5
Little louder, little louder, little louder, knockin'
A5                        G5
Little louder, little louder

(refr?o 2x)

Little louder (3x) knockin'
Nothin' works like you, oh oh
Little louder (3x) knockin'

(refr?o)
