Grace went on TikTok / Instagram and performed two songs. Well, actually she performed three, but the second one was more like five minutes of improvised stream of consciousness set to equally improvised ukulele-playing. We have chosen not to include this as a "song", but you can find at the 6:28 mark.
The third one was an original. She may have made a first draft of it on the spot in the live, but at least the music part of it appears a bit more polished, so she may have toyed around with the song a bit before. Anyway, she was so happy with that one, that she asked online if anyone had screen-recorded it. Fortunately, someone had.
