The Rattlin' Bog

Ho ro, the rattlin' bog, and the bog down in the valley-O
Rare bog, and a rattlin' bog, and the bog down in the valley-O
In that bog there was a hole, rare hole and a rattlin' hole
And the hole in the bog, and the bog down in the valley-O
And in that hole there was a tree, rare tree and a rattlin' tree
And the tree in the hole, and the hole in the bog
And the bog down in the valley-O
And on that tree there was a bough, rare bough and a rattlin' bough
And the bough on the tree, and the tree in the hole, and the hole in the bog
And the bog down in the valley-O
And on that bough there was a limb, rare limb and a rattlin' limb
Limb on the bough and the bough on the tree, and the tree in the hole
And the hole in the bog, and the bog down in the valley-O
