Ok, I've got a challenging (I think) song search for you. Does anybody know the origins or have a complete set of music and lyrics to the following:

Have a care, Mr. Bear
Don't you dare to take a bite of me
I shall scream so loud and quick
My Poppa shall fetch a stick
And he's not afraid of bears, not he.

Etc, etc. I don't know if this is chorus or verse. Sounds like English, or perhaps Irish Music Hall material to me. Anybody know this gem?

Thanks - Tim
