I remember most of it...

Willie Moore was a young man, his age 21
And he courted a damsel fair
O her eyes were as bright as a diamond after night
And wavy (raven?) black was her hair

He courted her by night and day
Till on marriage they did agree
But when he came to get her parents' consent
They said that it never could be

SHe threw herself in Willie Moore's arms
as often she'd done before
And little did he think when he left her that night
sweet Annie he would see no more

Sweet Annie was loved both far and near,
she had friends 'most all around
Then in the little brook before the cottage door
the body of sweet Annie was found

She was taken by her weeping friends
and carried to her parents' room
And there she was dressed in a shroud of snowy white
and laid in a lonely tomb

Willie Moore scarcely spoke to her friends, they say
Till at last (from them all he did part??)
And his last day was spent near his true lover's grave
where he died of a broken heart

I may also be missing a verse between her disappearance and the finding of her body, I have a feeling they looked for her for more than one verse...
