Conducting a musical experiment

Somehow, during December, I managed to miss a series of "holiday" videos posted at the CBC web-site.  I used quotation marks because so far, these videos have little to do with Christmas.

But that's okay.  As winter persists, beauty and brightness are never inappropriate or time-sensitive.  Let's start with a social experiment in a West Coast shopping mall.  You could say the experiment was conducted. It features the Hallelujah Chorus from Handel's Messiah, which can be enjoyed at any point of the year, so why not now?
