Tried the other version and it didn't work for me. This seems to work a lot better. 

Intro: (Played on mandolin, but this is how it translates to guitar chords)

D Dsus4 D Bm Asus2 Bm Asus2 D

         D
Well the hills are pretty and rollin'
        F        G            D
But the thorn is sharp and swollen
        D
And the man plays a beautiful whistle
       F       G       D
But he wears a prickly thistle
        D
Singing Li De Li De Li Oh Oh
       F     G        D
Well A Li De Li De Li Oh Oh
D
Li De Li De Li Oh Oh
       F     G        D
Well A Li De Li De Li Oh Oh

    D
The silver birches pierce through an icy fog
      F          G            D
Which covers the ground most daily
        D
And the angels which carry St. Andrew high
    F         G         D
Are singing a tune most gaily

    D
One sound can hold back a thousand hands
         F            G    D
When the pipe plays a tune forlorn
     D
And the thistle is a prickly flower
         F         G       D
Aye, But how it is sweetly worn
        D
Singing Li De Li De Li Oh Oh
       F     G        D
Well A Li De Li De Li Oh Oh
D
Li De Li De Li Oh Oh
       F     G        D
Well A Li De Li De Li Oh Oh
