Not that it will help you on this (although I'm sure you could get the individuals names if you had to) but there is an app for your phone called Easy Release that you can use if you want to in the future...
I think I have it on my iPad. I at least have something similar. I was thinking more of mounting it and selling it. I just think it's a great rodeo shot. Granted I'm biased slightly
