From Once Upon a Time Using Storytelling, Creative Drama, and Reader's Theater By Judy Freeman (Greenwood Publishing Group, 2007), page 61:

Old McTavish is dead and his brother don't know it.
His brother is dead and McTavish don't know it.
They're both of them dead and they're in the same bed
And neither one knows that the other is dead.

Oh, McTavish he died of the peritonitis.
His brother he died of chronic arthritis.
How both of them cried and both of them sighed
When each of them found that the other had died.
