Hi guys :) this is a really easy way to play this and it sounds right when I sing with 
it, so I hope it works for you too! Enjoy!
Capo 1:
G D/F Em7 Cadd9
Verse 1:
G                       D
He was the man of every hour
         Em7        Cadd9
He was a party all alone
              G           D               Em7     Cadd9
He’d give his jacket to a stranger in the cold
            G                 D
She was the beauty queen from dallas
                Em7       Cadd9
She could put a lion on a leash
     G            D
And before he knew himself
             Em7              Cadd9
She knew the man that he could be
Pre- Chorus:
                G      D
It’s never that easy
                Em7   Cadd9
It never seems right
                   G
When careful meets carefree
            D              Em7                 Cadd9
And in just 4 minutes they knew each other for life
And he said
Chorus:
G                    D            Em7
“Alright Nikki, it’s alright Baby tonight
Cadd9
you can let your hair down
G                   D            Em7
Alright Nikki, it’s alright Baby tonight
Cadd9
You can take a breath now
G                D
If you only live once
             Em7
Stay in the clouds
           Cadd9
Never come down
Trust me
G                   D            Em7
Alright Nikki, it’s alright Baby tonight
Cadd9
you can let your hair down.“
G D Em7 Cadd9
Verse 2:
           G.            D
She was an Angel craving chaos
          Em7          Cadd9
He was a demon seeking peace
         G
But they were each other’s
D                 Em7     Cadd9
toxic cure called codependency
            G                    D
He tried to dig his way out of a coffin
            Em7               Cadd9
‘cause she smothered him with care
G                    D
Before they lived in castles
           Em7       Cadd9
They were dying on a prayer.
Pre- Chorus:
                G      D
It’s never that easy

When careful meets carefree
            D              Em7                 Cadd9
And in just 4 minutes they knew each other for life
