The core of my QLab show file was the MTI tracks, sourced through MTI Player. I used QLab's disarm feature to ignore unused tracks rather than delete them. To create cuts in tracks, I duplicated tracks and trimmed them to create gaps inbetween.
I created the London bridge drone by using some auto-follows and clever grouping to allow easy cueing.
I premade my QL show file in the QL Edit software, allowing me to simply import my file in tech week. I laid out all 20 channels of RF and sent them into a mix bus, which I could then send all mics as a whole to where I needed to send them. I had quick control of all hanging and backstage mics, and my talkback mic.
