KXTV, the Tegna station in Sacramento had their morning news Anchors singing and dancing in the station's parking lot to shoot an Oscars promo.
The station went through a lot of trouble and time to shoot the promo. And they did make a big assumption that the entire audience saw LA LA LAND (for the record, FTVLive has not seen it).
I still remember the days of Walter Cronkite and Ed Murrow dancing and lip syncing in the alley behind CBS.
Oh wait.... that never happened.
