If the government tried to put everyone in the slammer or on trial for playing music under copywrite protection, they would have to round up every small band in the country, including solo performers, and that would clog up the court systems for years. How many small clubs or bars would have to close for lack of entertainment? It would be a bigger mess than trying to ship out every illegal immigrant. I would suppose not every Elvis impersonator gets permission to use his personna. Still, what's right is right, and I guess if you're going to make money from performing, maybe you should hire someone to keep an eye out for the revenueers!
