I had the same idea but with no beer in mind, I'm using an ammunition can. I am though, having circuit problems. Below is the wiring diagram that I used. Tell me if i need to change anything because it buzzes and the amplified audio is choppy.

Good Job! Here is a suggestion. Try hooking up a solar cell and a rechargeable battery and keep the battery charged.
