Early “For Good” leaks

i remember early this year around Feb-April… there were a lot of supposed leaks for the song “For Good” circulating around on TikTok, the Elphaba singing “for good” sounded an awful lot like Cynthia, but it wasn’t, some people say it was Jessica Vosk but i’m not sure..

What really drew me into it and makes me still think about that singer was the way she sang “being my friennnddd”

which is a line Cynthia sings differently.

Does anyone else remember these alleged leaks, and do you know who the singer who was in them?
