[from the very weird angle of this feed, it seems like somebody accidentally hit their guide record button! How clumsy. That certain somebody isn't completely visible right now; it kind of looks like all those youtube videos were all you can see of a person is their upper chest up to their chin as they play the piano.
It looks like that because there is, in fact, a piano! And someone playing it! Well, not right now. The pianist looks like he's not quite ready yet, loosely playing some notes with one hand. Some of you might even recognize it as the ending of the Beatles' classic "I Wanna Hold Your Hand"! But most of you probably don't. It's a bit slow to properly recognize without accompaniment.
Finally, Kurt sits properly on the bench and starts playing a slow,
mildly creepy
song. (Fun fact: it is closer to the first link than the second, for obvious lack of other instruments reason.)
About thirty seconds in, Kurt starts to sing, and thus some of you might finally recognize it as a very odd reimagining of Elvis Presley's "You Were Always On My Mind"! Most of you probably just think it sounds odd and weird. And sad. Kurt sure sounds sad, at least. He sounds ridiculously honest when he sings "I'm so sorry", and those sure look like tears from this weird angle! How depressing.
Once the song is over, Kurt stays still for a few seconds before taking in a shaky breath and lifting a hand to his face and wiping his tears away.]
... Dad...
