I've never heard more than a simple "Hi ho", with the standing up. I learned to do it that way from Iain Grant and Jimmy Greenan at Sandy Bell's around 1990. Iain mentioned a specific performer who started it, not all that long before, but I forget who it was.


The Google ad I'm getting along with this message says

   Why is the rapture a lie?
   Jesus Christ will return to rule earth with the resurrected saints.

Maybe they know something about the significance of the standing up that we don't.
