With the skill of the practised disbelief-suspending theatre-goer, I was aboard one of the Galactic Futures Organisation's last transports, having elected to make the jump from this world, where the human race had exhausted natural resources and succumbed to conflict, to New Earth, where the promise was of verdant greenery, azure oceans and peaceable communities kept in a constant state of wellness by a benevolent administration.
Grid Iron Theatre Company's latest site-specific extravaganza, Leaving Planet Earth, is all about that tension between the love of the familiar and the devil we know and the promise of a brave new world in which we can all start afresh. Written and directed by Catrin Evans and Lewis Hetherington, it could hardly be more pertinent for contemporary Scotland - have a look at the website leavingplanetearth.com if you are not able to experience the live show.
It is concerned with the implications of that choice, and the different decisions made by Vela (Lucianne McEvoy) and her sister Sinead (Muirreann Kelly, whom we only see on film). How much should we believe the propaganda about the fate of the Old Earth? What evidence do we really have for the perfection of life in a pod "beyond the wall" on the New Earth that GFO has located in an outer arm of our own galaxy? Could the convincing details of a new world be as easily produced "for real" as they are here by a theatre company? Or is that cynicism a manifestation of our innate conservatism and timidity in the face of an opportunity to make the jump into a bold new future?
Some hours later I was unsurprised to be deposited outside the same conference centre in the midst of the same old festival. So I probably should also be unsurprised the debate of the week was about the alleged failure of the Edinburgh International Festival to engage with issue of Scottish independence.
Get with this year's programme, earthlings, before you start worrying about the next one.
