Very sweet song, and it's easy to play (:
I play it with strumming DDUUDU


INTRO:
D

VERS1:
E                         A
I knew a girl in shades of blue,
D        Dsus4           G
Who broke my heart and said “We’re through”
E              A
Waiting for a girl like you
D            Dsus4      G
To change me like the weather
E                  A
Since she left me high and dry
D        Dsus4   G
Split me like a Gemini
E                   A
All those days are passing by
D     Dsus4        G
Like flowers in December


CHORUS
E                  A
Friday is forever, we belong together
D           Dsus4
So come on, come on,
G
And don’t you say never
E                       A
If you go then I know, there is no tomorrow
D           Dsus4
So come on, come on,
G
You should know better
E            A
It’s right, it’s time for you and I
E                  A                       D
Friday is forever, we should be together tonight


VERS2
E              A
No more living in her head,
D        Dsus4   G
No more crashing in my bed,
E                 A
I’d rather go with you instead
D     Dsus4        G
Don’t care where we end up
E              A
Hold your body close to mine
D     Dsus4         G
Blame it on the blood red wine
E                  A                     D    Dsus4   G
It takes a week to finally find if that Friday is forever

CHORUS
E                  A
Friday is forever, we belong together
D                  Dsus4
So come on, come on,
G
And don’t you say never
E                      A
If you go then I know, there is no tomorrow
D           Dsus4
So come on, come on,
G
You should know better
E            A
It’s right, it’s time for you and I
E                                         D
Friday is forever, we should be together tonight 


BRIDGE
G            E            A    -A-A       D    DD
Don’t be afraid, we will stay-ay-ay this way
G          E     -E     -E        A            G
Don’t ever change-ange-ange, I’m in love with you
Whoa

G
And don’t you say never

We should be together tonight
