The footage still has to make it home to be seen. Just because something is recorded does not mean that every person will eventually see it. Most jumbotron footage is boring, people generally do not seek it out for casual entertainment. It very likely would be lost had it not gone viral.

I mean if it hadn't gone viral there's at least a chance it wouldn't have made it back to the wife.

I mean by that logic just going to the game would have outed them, as hundreds of fans saw them together... Unless I'm missing something, was this cold play concert long term televised or something?

Bottom line is, would this be in a position that anyone who knew who he was, would have seen? Unless the recording was something super substantial that say tens of thousands would have noted it in his home town or office, or millions world wide to the point where there's a reasonable chance that his wife or someone who knows the family would have been able to call him out, it probably wouldn't have gone anywhere.
