Because I believe it to be the case. Plenty of people asked how it all ended, and there was a description of what happened - but no video.
With all due respect to James, he may be confusing it with pretty much every other sit-up breakdown every time they had a power cut after 2007. The power goes out, the channels go blank for a short while and the on-air output goes crazy while all manner of things get shown including breakdown slides and the music in question for a good half hour or so. There are a few examples of this on YouTube captured while Sit-up tried to get the channels going again. From what was posted at the time the networks were in the middle of flogging something when they went off air with little notice so it's entirely plausible somebody flipped a power switch somewhere.
I’ve got another breakdown from 2008 on an old PVR where they come back from a power cut to Peter Simon in Larry Grayson mode and while he is doing his little ditty, the studio lights followed by the monitors behind him keep going off and on every 10-15 seconds. The monitors would turn to static as the lights went off.
