I saw a clip of the quick change last week, and the next day was invited to see the show in Nashville for Mother’s Day with my mom, so I was waiting the whole first act for this!
This is probably Janneke Ivankova not Sabrina nor Willemijn, You can kind of tell through the face shape but does sound like Willemijn but one of the long notes at the end tells me it's not Willemijn because Willemijn does this really high-pitched riff near the end. I watched Willemijn like a week ago and it was great.
I want to tell you that just at the end of the year I found this great gift, for months I have been searching for "Edem Espinosa - Defying Gravity" and I couldn't find anything new, but just now I found this. Thank you very much, I hope with this to start 2024 with a flourish.
