New Avett tune called "Spell of Ambition". First played on 3/20/14 in Savannah, GA.  
I based this tab off of a YouTube video which can be found here: https://www.youtube.com/watch?v=_wpuUOMD79I 
As it is a new song with potential to change, I'll try to edit as necessary. 
Also, during the "my words" section, Seth does a straightforward walkdown on the C chord to the G. 

Standard -  
capo 5 

G                Bm         Em 
I fell under the spell of ambition 
         C            G 
And not even for money 
         Bm               Em 
Just to have a chance to listen 
           C 
To the back rows 
         G 
Say honey,  
         D7              C              D7           
You’re surely worth the price of a ticket 

G           Bm               Em 
 Then with nerve and such pretension  
   C          G 
I used religion 
     Bm         Em             C            G 
To explain a vision and this blessed position 
   D        C            D 
To be an object of affection 

C   G     C        C 
My words feel so plain 
C      G       C      C 
And rehearsed when I say 
                 D7 
Would you forgive me? 

G        Bm            Em 
 Is the fury of the mother 
C                              G 
 Does it not live in the daughter? 
         Bm            Em 
Is the darkness of the son 
     C                G 
Not seen in the father? 
   D               C 
I cast a perfect mask 
              D 
But why bother? 

G            Bm             Em 
 Cause whatever girl I run with 
        C                  G 
Or at least am in love with 
      Bm               Em 
Will have to ask herself 
      C               G 
What can I put up with? 
     D               C             D 
And do I call him stranger or husband? 

C    G     C        C 
My words feel so plain 
C      G       C      C 
And rehearsed when I say 
                 D7 
Would you forgive me? 
                  C             G  G/F# Em 
Would you let it roll off your shoulders? 
C                                   G 
 Would you let it fall to the ground? 
        C            G G/F# Em 
Let me know when it’s ooover 
Am                D7 
 So I can set it down 

G                 Bm           Em  
I fell under the spell of ambition 
         C            G 
And not even for glory 
         Bm                   Em 
Just to have the room’s attention 
     C           G 
And tell my story 
      D                  C             D7 
And let them sort the sadness out for me 

    C   G     C        C 
And my words feel so plain 
C      G       C      C 
And rehearsed when I say 
               D  
Would you forgive me? 
               C 
Would you forgive me? 
               D7 
Would you forgive me?
