I did my best to listen to the song and do it justice. 
Both verses have basically the same chords. 
To end it, just strum the chords of the last line once. 
Personally I strum each chord only ones in all lines.

 Enjoy!

Verse 1

   Bm          G     D          A
Of all the money that e'er I had

  Bm        G   D      A     
I spent it in good company

    Bm          G     D          A
And all the harm that e'er I've done 

  Bm  G  D       G      Bm
Alas it was to none but me
 
     D    G    D       D    G  D
And all I've done for want of wit 

   GMaj     Bm     G       A
To mem'ry now I can't recall 

   Bm       G      D        A
So fill to me the parting glass

       Bm   G   D       G       Bm
Good night and joy be with you all

Verse 2

Of all the comrades that e'er I had
They're sorry for my going away
And all the sweethearts that e'er I've loved
They'd wish me one more day to stay 
But since it falls unto my lot
That I should rise and you should not 
I'll gently rise and softly call
Good night and joy be with you all
