Well, there are a few thousand drinking songs out there. The Digital Tradition database doesn't carry tab, but check Google for 'guitar tablature" and you should get a few sites that do. I think OLGA.net will hopefully meet your tab needs.

As to "moonshine", if you provide some lyrics then we might have a better shot at figuring it out for you. The most likely suspect (because it's on the list of 'top ten most played drinking songs' worldwide) would be The Moonshiner, but again - without more to go on, I'm kinda grasping at straws.

Hope this helps.
