At the first run there seem to be some issues with the lighting as Yianna is not lit during significant parts of the second verse. She's wearing the same dress and also has the blue hand we saw on Monday.
The issues with the choreography in the bridge still remain though and I still think it looks unnatural to not have the backings appear on stage at some point in this performance.
During the first rehearsal another issue existed with the high notes - it seems better now in the hall, but can't be completely sure. It might as well not have been resolved yet.
