[Intro] - F#m

[Verse] 
F#m     C#m               Bm     Bm7 D Bm7 Bm
You said you'd marry me, if i was 23
 Bm7  D       Bm           F#m
But i'm one that you can't see if i'm only 18
F#m      C#m           Bm    Bm7 D Bm7 Bm
Tell me who made these rules
Bm7  D       Bm   
Obviously not you
       F#m            F#m F#m
Who are you answering to?


[Chorus]
                            A
Ohhhhh jenny don't be hasty
                           F#m  Bm
No don't treat me like a baby
                            A
Let me take you where you'll let me
                            F#m  Bm
Because leaving just upsets me



The rest of the song is basically the same pattern.
except the other chorus's end with Bm D instead of F#m Bm 
at the 'Because leaving just upsets me' part.
