Pretty sure this is right, sorry if it's not! First time doing this and there 
wasn't a good one on here. It's so easy, just repeat the same three chords throughout!

Bb Gm Dm x6

         Bb        Gm       Dm
When I was younger, I always thought
I could be someone if I tried enough
When I was younger, my father said
Wear a smile, show respect
When I was younger, you never said
When I was older, I'd feel helpless
When I was younger, you shone the light
And now that I'm older, it doesn't shine bright
When I was younger, you always said
That as I got older, you'd always be there
             Bb Gm Dm x4
I'm singin' ooohhh 
            Bb        Gm       Dm
When I was younger, I used to care
About everything that my father said
When I was younger, you even told me
To show evil, the utmost respect
When I was younger, I never thought
That when I was older, I'd see you give up
Now that I'm older, I carry the torch
Just promise you'll stand and you'll be strong

             Bb Gm Dm x8
I'm singin' ooohhh

            Bb        Gm       Dm
When I was younger, I never thought
When I was younger, I never thought
That when I was older I'd fight your wars
That when I was older I'd fight your wars
I'll do it for you, I'll do it for you
I'll do it for you, I'll do it for
              Bb        Gm       Dm
When I was younger, I only dreamed
That when I got older, you'd be proud of me
When I was younger, I promised you both
That when I was older, you'd be proud of me


You Me At Six until I die!
