Yeah, any re-release would need record company permission. After all, they're the ones who own the rights to the recordings. I very much doubt they'd allow that. It's amazing really that they allowed the fan club to do it. I strongly suspect that that's why the club always stipulated they could only be sold on to other fan club members and at face value and why the clamped down on eBay auctions etc.
It really is a shame because they're a treasure trove of fabulous performances. My biggest complaint about them is that, because they were recorded for the band's own use, they didn't mike the audiences. As a result, we hear these storming, intense performances followed by near silence, as if they were either playing in an empty room, or the crowd were utterly unenthused which, of course, we all know was nonsense.
