My answer is "Probably not", even though I guess it will be at a convenient time for me.
Honestly, I'm not too much interested. But on the other side, I watched Diana and Charles' wedding many years ago (was more or less 'forced' to it, because my friend's foster-mother watched it and we were in the same room). I also watched bits and pieces of Diana's funeral. Her death was really a kind of "Kennedy moment" - you know, a certain point in time, a landmark that everybody would remember for their whole life.
So, it clearly is a big current event, and maybe I'll watch parts because of that. But my revolutionary heart says this wedding shouldn't be of any importance, the concept of monarchy is so outdated that everybody should boycott it.
