Let me put it this way: if I get the Tristan tickets for next year (one applies in September), I'll try to get four. There is no guarantee it'll work out, but if it does, then you have a ticket. And I'll take you up on Paris if it does.

I just aquired the Furtwängler & Flagstadt (1952) one myself, in Bayreuth, and am at the moment listening to it.
