This isn't a train wreck story, but I find it humorous anyway. I'm helping my old grade school with their musical, The Music Man, and we just had two performances for the school. I got there this morning, and changed the batteries in the 10 shure wireless lavs I'm using. The director bought these no-name batteries I've never heard of before, but, what the heck, we'll use them anyway. First show goes off without a hitch. Second show, I'm starting to get some fuzz from the wireless, and the receivers are switching antenneas to find a good signal. 10 minutes later, all the recievers say "low battery", and start loosing the carrier signal all together. By this time, I'm in a bit of a tizzy, as there's no time to get back there to change batteries. Luckily, I still had enough common sense to suggest having an intermission, then ran backstage and changed batteries with whatever was on-hand. As a side note, this show was not supposed to have an intermission. Oh well, the kids didn't notice, so, I guess I did my job correctly. Now, anyone else have interesting wireless mess-ups?
