UNFORTUNATE GIRL, THE                Trad. From Norma/Lal Waterson CD

As I was a-walking one fine summer's morning, as I was a-walking one midsummer's day.
I met a young female all dressed in white linen, aye a-dressed in white linen and cold as the clay.
Oh Mother oh Mother come sit down beside me, now come sit down beside me and hear me sad case.
For I have loved a soldier who has lately deserted, and he's gone and he's left me in shame and disgrace.
Oh daughter dear daughter why didn't you tell me, now why didn't you tell me of it in time?
I could have bought salts, aye or the pills of white mercury; you're a true-hearted girl but cut down in your prime.
Come doctor, dear doctor, come fill up your bottles, come fill up your bottles and make them quite dry.
For me bones they are aching and me heart it is breaking, in this shame and disgrace I'm afeard I must die.
Have six jolly sailors to carry me coffin, have six jolly soldiers to sing me a song.
Have six bonny lasses carry bunches of roses, so that you can smell me as I go along.
Then play the pipes slowly and beat the drum slowly, and sing up the Dead March as you go along.
Take me to the graveyard and throw the sods on me,I'm a true-hearted girl and I never done wrong.
