[Verse]
D             C                       G                D
Just me and a street light, watch the world go rushing by
D                C                 G                D
Cars are racing, people walking, I swim against the tide
D                C                    G            D
I never felt so alive before, I never felt so all alone
D               C               G               D
This town could be a prison but this town is my home


[Refrain]
D C G G6 D


[Verse]
D              C           G                   D
In this sea of sameness, I don’t feel like the rest
D         C              G                 D
Even if I wanna fit in I know I’d fail the test
D                   C             G            D
But my friends will stick with me tomorrow and today
D                     C                         G                  D
Through the bad times and the good, through the blue skies and the gray


[Pre-Chorus]
G           A      G                A
We might complain, here's where the story will remain
G                 A           D         A       G
These streets are energy, the night can set you free
G                A          D         A     G        D A G
When I’m in this place, I’m whoever I wanna be
            E5
This is our town


[Chorus]
            D
We're gonna knock, knock, knock
G
Knock this town
            C                G
We're gonna knock this town again
            D
We're gonna knock, knock, knock
G
Knock this town
C               G
'Til the bitter end
            D
We're gonna knock, knock, knock
G
Knock this town
        C            G
'Til we come around again
            D
We're gonna knock, knock, knock

Knock this town
C                      G                D   C   G G6 D

[Verse]
D               C                     G               D
Can’t go to the fancy places, they’ll point us to the door
D                C                    G                D
Can’t afford the high life, we’re too close to fucking poor
D                    C            G           D
But there are places I know where no one ever goes
D             C              G                D
In this city, in this life I walk a different road


[Pre-Chorus]
G          A                G             A
Standin’ beneath the light, we’ll own the streets tonight
G               A                  D       A        G
Drinkin’ in the sounds and sights, knowing that I’m home
D                A              D    A       G            D A G
Breathin’ in the glow, it’s the only world I know
            E5
This is our town


[Chorus]
            D
We're gonna knock, knock, knock
G
Knock this town
            C                G
We're gonna knock this town again
            D
We're gonna knock, knock, knock
G
Knock this town
C               G
'Til the bitter end
            D
We're gonna knock, knock, knock
G
Knock this town
        C            G
'Til we come around again
            D
We're gonna knock, knock, knock
G
Knock this town
C                      G                D
Knock this town, we'll knock this town again

D                     C                    G                 D
I don’t know what I’m thinkin’ now, it’s a different kind of blue
D           C                 G               D
Everyone is out tonight but I wish I was with you
D           C                     G               D
I’ll stay a little longer, listen to the world go by
D          C                          G                D
I love the woods and fields, it’s the soundtrack of my life


[Pre-Chorus]
G             A      G              A
It’s got some flaws, then again, so do we all
G           A          D            A   G
We might complain, but here’s where I remain
G          A                 D     A       G        D A G
Giving its strength to me, I never felt so free
            E5
This is our town
