Not sure what you mean, Kevin. Well, I suppose if your talking about organized union workers who do demos (shocked to hear there's a union for that).

Like Heather, you pay her and do whatever you want with it. She doesn't say a thing about restrictions, and I'm guessing that's the case with most folks (independents, for sure).

I mean, Geez, ANYBODY who can sing and pick can run an ad to do demos, and there would be no regulations whatsoever (aside from Uncle Sam wanting his cut).
