All we can do is speculate but if their old contract the record company didn't have any revenue as far as touring and merchandising went then it would have created a murky area where even though they owned the masters of the songs being performed they wouldn't get any piece out of this "official bootlegs" being released so to speak. My guess is that now that the contract is renegotiated and everybody get a piece of the pie, an agreement could finally be made....
