Thousands of years ago*, when I was but a smallish child in Chicago, I used to regularly hear a "singing commercial" for Edelweiss beer:

Drink Edelweiss
It tastes so nice
(forgot this line)
Drink Edelweiss

Which I revised to:

Drink Edelweiss
Kills rats and mice
It's worth the price
Drink Edelweiss

As I recall, Edelweiss was a local (Chicago) brand, and was still
being produced by the large brewery that acquired the label into the (nineteen) nineties.
