There is no history of the MEC, because it's fiction...

From Ariel, on a CBC interview, plugging "From Coffee House To Concert Hall"

She said that The MEC actually started off as Stan trying to write a speculative fiction story about a bunch of guys salvaging a space ship out of a low doangerous ourbit I seem to recall...

Stan was a big fan of hard SF...

Fortunatly for us, the story never got finished, but the song that it grew into did... and what a hell of a song it is...

And the line is

We patched her rents, stopped her vents, dogged hatch and porthole down...
