Generally speaking, to include "Record Rights" at the initial stages adds approx. 10% to the usual costs. However, an "after-the-fact" deal requires a 100% re-pay. So you can see, that it is a substantial difference. Now it is possible to negotiate a limited number (say a few thousand units), but once that number has sold out, that's it! Unless you are willing to pay the full 100% plus a potentially hefty penalty fee - so in that scenario, you end up paying the discount fee, then the 100% fee, and a penalty. That usually means that the material will be gone forever as there would be no way to recover those accumulated costs. It's best to get the rights at the start. But if I have make a deal after the fact, I want to make sure that it is a lifetime deal and not limited to a select few. I want this stuff available for generations to come - way beyond you and I.
I do go to the parks quite often (fun / business - I have no dividing line). But usually, Cast Members seek me out - either through company channels or the internet (as you have by posting here). Also, though I only post on this site, I do read the other major Discussion Forums whether it has anything to do with music or not.
