I've only heard a very short clip of this but this is what I think the lyrics and chords 
are - the last two and a half lines are just supposed from what I've heard so I'll 
change it when I hear the full version if I have to.  It's a fun and catchy song to play though :)

Intro - D x4

     G                 A           D
Well I’ve never been a man of many words

            G               A                    D
And there’s nothing I could say that you haven’t heard

F#                                    Bm  A G
But I’ll sing you love songs ‘til the day I die

            D
The way I'm feeling

  G          A  D
I can’t keep it inside

            G                  A                   D
I’ll sing a sweet serenade whenever you’re feeling sad

      G            A                      D
And a lullaby each night before you go to bed

F#                       Bm   A       G
I’ll sing to you for the rest of your life

            D
The way I’m feeling

  G          A    D
I can’t keep it inside
