I was in Pomona at a Glass House concert Tuesday, minding my own business, when suddenly news broke out: The singer invited a fan from the audience to come onstage and sing a portion of a song about Glendora.

You can read about that in my Sunday column, as well as about my Ontario film series. I shot a one-minute video of the impromptu performance, which you can watch here (warning: adult language!); a full version from closer to the stage can be viewed here.
