Misc Unsigned Bands - Fallout New Vegas Joshua Sawyer - Home On The Wastes chords

This great Fallout song is played just like 'Home On The Range"[3/4 time].There 
are some difference, though. The tune for example (E). I think my chords are not 
100% correct, but.... :)
Don't foreget to comment and add me to your friends! Thanks!

Intro:
E B7
E A7 E


E                            A
Oh, give me a home where the bighorners roam.
          E                F#7        (B) B7
Where the mole rat and the fire gecko play.
       E                 A
Where seldom is heard a discouraging word,
        E           B7         E
And my skin is not glowing all day.

Chorus:
E     B7          E
Home, home on the wastes,
                           F#7     (B)B7
Where the mole rat and the fire gecko play.
      E                    A
Where seldom is heard a discouraging word,
        E             B7       E
And my skin is not glowing all day.


E                                  A
Where the rads ain't too high, the water's not bad,
    E             F#7        (B) B7
The radscorps are playful and mild.
       E                      A
Oh, I would not exchange this home on the wastes,
     E           B7         E
For all the big cities so wild.


Chorus:
Home, home on the wastes.
Where the Master's great armies once played.
Where seldom is heard a discouraging word,
And my rads are not rising all day.

Home, home on the wastes,
Where the mole rat and the fire gecko play.
Where seldom is heard a discouraging word,
And my skin is not glowing all day.
