My biggest memory of working the sound system was when I wasn't baptized and in high school. I've always been into that kind of stuff and have actually worked sound for various concerts since then so I actually did enjoy doing the work and was happy to do whatever I could.
I wasn't baptized which was apparently a requirement to work sound at the two day assemblies but they still had me running wire and setting up remote speakers for the first time. For some reason they didn't set up the night before and they guy who stored the system didn't get to the auditorium until an hour or two before it was supposed to start. Once he got there and unloaded he realize that he left the diagram to set it all up at home. The program was supposed to start in about 45 minutes and he lived over an hour away. Anyone see a problem? All the brother that were working on the sound department were called together to see if anyone knew how it worked. Nobody did so they just started asking for suggestions. Long story short, a 15 year old kid (me) ended up going from just running speaker wire to setting up all the controls and power amps in about 20 minutes because nobody else could figure out how to do it. I still wonder what would have happened had I not been there that day.
A couple years later when I started getting into trouble for having girlfriends they told me I couldn't work the sound system at my congregation anymore. That went on for about a week or two when middle school kids tried to do it because the normal brothers were busy doing other stuff. After getting complaints about how horrible things were going I was told that I would be allowed to start doing the work again since I had been repentant. I just told them that I didn't really want to do it anymore. Hey, if they're going to punish me for being a normal kid and take away the one thing I enjoyed doing then they can stick with the crappy work that comes when you let other people do it.
