This is how it's recorded on "There But For Fortune" The chord structure is the same 
the song. Enjoy this great song!

C              Am                F            C
Oh I am just a student, sir, and only want to learn

         Em                       Am                  D7 (use thumb)
But it's hard to read through the risin' smoke of the books that you like

   G
to burn

       C              Em              Am             F
So I'd like to make a promise and I'd like to make a vow

          C                     Am            F     G
That when I've got something to say, sir, I'm gonna say

   C
it now
