It's more likely we'll find 100 unreleased LP live shows than this particular Xero show. Especially if the years go by, some shows just get lost after all this long time, it happened many times before. Of course it's just a matter of finding something, but if no one has it in an online list or is selling it somewhere it's almost impossible to track down.
Over the last years a LOT old shows popped up, no one would have ever expected we'll get them. You never know what's going to happen, but personally I highly doubt we'll get this one. But we know the band owns recordings of their first shows. They stated that many times. Maybe we are lucky someday and get some more.
