The Farmer in the Dell vs. A-Hunting We Will Go

Omar would often whistle while walking Baltimore streets at night, as a sort of warning to others that he was there.

I used to always hear this as "The Farmer in the Dell", until someone pointed out it's actually "A-Hunting We Will Go". Now that makes more sense! Omar isn't a farmer, he's a hunter.

The thing is, "The Farmer in the Dell" and "A-Hunting We Will Go" have identical melodies.
