Twas in the merry month of May
              Am           G
When green buds all were swelling
       Dm                C
Sweet William on his death bed lay
              G       C
For love of Barbara Allen
             
             C     
He sent his servant to the town
              Am            G
To the place where she was dwelling
        Dm                 C
Saying you must come to my master dear
        G                 C
If your name be Barbara Allen

       C
So slowly slowly she got up
      Am               G
And slowly she drew nigh him
          Dm             C
And the only words to him did say
       G              C
Young man I think you're dying

         C
As she walked slowly o'er the field
              Am           G
She heard the death bells knelling
          Dm               C
And with every stroke it seemed to say
      G              C
Hard hearted Barbara Allen

               C
Oh mother, oh mother make by bed
          Am        G
Make it long and narrow
              Dm          C
Sweet William died for me today
           G               C
And I will die for him tomorrow

(And then I decided to make some changes here...)

       D                       
They buried her in the old churchyard
            Bm     A
They buried him beside her
     Em                     D
And from his grave grew a red red rose
              A             D
And from her grave a green briar
          
              D
They grew and grew to the steeple top
                 Bm      A
Till they could grow no higher
      Em               D
And there they tied a true love's knot
      A              D
Red rose around green briar
