I have an odd question...

Oh gosh, never mind - the wife found one for Aliens in 5 minutes...

 Aliens: The Musical

Ok good, you found it. 

Aliens: The Musical... I've just watched it. I can't express the shock I'm facing now. :)

The urns are secreting the same xenomorph resin.  Creating the "perfect" ecosystem for growing eggs and am alien environment, dare I say "hive".  Although I believe the xenomorph is ultimately a solitary hunter, and not just a hive bug. 

Yes but can they hold a tune?
