While I'm here, I might as well make another request. I got this sample a while back: link
I don't have a copy of this show, but if anyone has a copy that matches this sample (of course, better is always welcomed!), perhaps they could share it.
I'm quite sure I have the same version listed on Queenconcerts. At least, time tracking is the same. It is the common version circulating on the hub and on Queenzone. I rate it as C+ at the most and certainly not as B-. So the recording listed on queenconcerts is most likely not an upgrade.
