Officially, I wasn't even there (really, no contract, no program, nothing). Realistically, I was the non-frazled ASM/Costumer/Propsmaster/Fly[which consisted on tie-line and carabiners, and worked beautifully].
On that particular show, I pulled my script (which I thankfully had mostly updated), and used an actor who wasn't in the first act, but actually knew his way around a theatre as a second set of hands. We pretty much had to rely on both board operators to be in synch and move things based on when the lights went up or down. Not a hugely complex show, just managed oddly.
I came in late to the production, so trying to re-arrange the system wasn't a brilliant idea-but am working with the director of the next show to see what can be done to increase the level of sanity (day job commitment keep me from SM'ing the next show)
