From the 1970 album Magnetic South. I'm not sure about the key, i think he plays 
with a Capo in fret 1. Suggestions: prietomartin@gmail.com

    F                       A
Whoa, Mama Nantucket, she tried to kick the habit
          Ab          C          F
But she couldn't and she got stung 
                               A  
I tried to relieve her, But she wasn't a believer
     Ab            C     F
Until she found another one 

(Chorus)
D                              G       C           F
Da-do-da-li-da-lo-da-la-hee I love it here on the range
A                            Ab       C           F 
Oh-my-ty-yi-yippee, I would love it more if it changed
Da-do-da-li-da-lo-da-la-hee I love it here on the range
Oh-my-ty-yi-yippee, I would love it more if it changed

Oh, Bobby with a dollar, he was sure he found the answer
But it might take a little time
Playing follow the leader, he was sure would be a winner
But I had other things on my mind

(Bridge)
    Ab            C        F
Oh, I see all the people running
Ab          C         F
Coming from miles around
A                         G
Everybody's singing a different tune
Ab                  C   
See them all fall down

Well I don't like to quarrel but what about tomorrow
Will it be the same as the past
I keep on hoping that something will happen
And I hope that it happens fast

Chorus x2

Yes, I'd love it more if it changed!
