When does a bird sing? Compare the sky behind the capitol building in the "official" inauguration video when Gaga starts to sing with this amateur video.

The balcony video is cloudy - he says early on that Klobuchar and Harris "speak". The only speaking Harris does is her oath in the official video - which is after Gaga sings, and that is the moment the weather turns sunny. So how can balcony man hear Harris speak in the gloomy weather?
It's possible he misspoke, but that is definitely interesting! Nice catch
