Just basic chords you can use for the song, nothing complicated:-) 
Only four chords used - Am F C G
Capo 1 (or higher depending on how you wanna sing it :P)

Am F
Oh, 
         C  G
I'll let go, 
               Am    F     C
I'll fight for you until I drop 
       Am    F
So get ready, 
           C      G
My love is steady
         Am
It won't slow
    F        C 
And it won't stop 

Am F           C      G
   Maybe I'm a mad man  
Am F           C                  Am
   Maybe I'm a bad, bad, bad, bad man
    F               C      G
But you won't see a sad man 
            Am         F  C
When you're looking at me 

Am F                C     G
   They can call me crazy
Am     F              C               Am
   But what good is a life behind the door
    F                C      G
And I've been living lately
            Am         F  C
When you're looking at me

Am F
Oh, 
         C  G
I'll let go, 
               Am    F     C
I'll fight for you until I drop 
       Am    F
So get ready, 
           C      G
My love is steady
         Am
It won't slow
    F        C 
And it won't stop 

             Am         F      C    G 
It's like my nerves are set on fire 
            Am           F     C
It's like a fuse growing in my brain
           Am         F         C     G
The sun is rising and we're not tired
         Am      F      C
We'll be dancing on for days

Am F           C       G
   Maybe I'm a mad man
Am F           C                  Am 
   Maybe I'm a bad, bad, bad, bad man 
    F               C       G
But you won't see a sad man 
            Am         F  C
When you're looking at me 

Am     F              C      G
   And now feels so amazing 
Am       F           C           Am
   We're vibing on a higher atmosphere 
    F               C     G
And you can call me crazy 
            Am       F     C
But it's so beautiful from here

Am F
Oh, 
         C  G

       Am    F
So get ready, 
           C      G
My love is steady
         Am
It won't slow
    F        C 
And it won't stop 

             Am         F      C    G 
It's like my nerves are set on fire 
            Am           F     C
