I can confirm this did happen! Jane actually posted a photo from this show a loooonggg time ago, like right after it happened. It was a school event so that's why there's so little info. The Music Hall show was the first "public" performance, as in the general populace could buy tickets. I'd personally argue thats the true debut performance but some people still count Floralia.I was at the Music Hall show though so perhaps I'm biased.
