Dear Robin,

Here are the guitar chords to the first verse and chorus of the version that I know. I got this from fellow Mudcatter, Den (thanks again, Den, if you're reading this!):

(Em)Oh a maid going to (D)Comber
Her (Bm)markets to (Em)learn
To (G)earn for her (D)mammie
Three (C)hanks of fine (Em)yarn
She (G)met with a (D)young man
(C)Along the (Em)highway
Which caused this young (D)damsel
(Bm)dally and (Em)stray

Chorus:

(Em)Sit down (D)beside me
I (Bm)mean you no (Em)harm
(G)Sit down (D)beside me
this (C)new tune to (Em)learn
(G)Here is three (D)guineas
your (C)Mammie to (Em)pay
So lay by your (D)yarn
Till the (Bm)next market (Em)day

I hope that helps. And great good luck to you with the bazouki.
