Can't find anything in the thread re 'Down in Demerara' which seems to be a relative somewhere in the mix.

There was a man who had a horselum, had a horselum, had a horselum
Was a man who had a horselum, Down in Demerara
   And here we sits like birds in the wilderness, birds in the             wilderness, birds in the wilderness,
Here we sits like birds in the wilderness
Down etc.

Now that poor horse he fell a-sickalum

Now that poor horse he broke his legalum

Now that poor horse he went and diedalum

Any thoughts on this?
