It's been a while since I sang this accompanied but something like the chord version below would work.

This version is, I believe, an 8 line verse rather than 4, as below.

(D)It fell about the (G)Lammas (D)tide,
When the muir-men (A7)win their (D)hay,
The doughty Douglas (G)bound him to (D)ride
Into England, to (G)drive a (A7)prey.
He (D)chose the Gordons (G)and the (D)Graemes,
The Lindesays, (G)light and (A7)gay;
But the (D)Jardines wadnae (G)wi' him (D)ride,
And they rue it (A7)to this (D)day.
