FJL, I haven't kept up with those videos for years - so would have no way of knowing if it had spiked.
Do you have a Mac? On the MAC, when I'm in the account the video is on, there are two blue rectangular boxes at the bottom right.
One says ANALYTICS and the other says EDIT VIDEO.
ANALYTICS will give you lots of info about number of recent views, and you can toggle for other period lengths.
EDIT VIDEO is strangely named, as it just means Edit the text around the video, and change the choices you've made - not edit the video itself, it seems.
