I think Seven Wonders was cut to shorten the set. Stevie always does this every tour. I will NEVER forgive her for dropping Stop Dragging My Heart Around midway/late Enchanted Tour
I think Songbird was cut for a different reason. I saw Chris wearing a black glove during parts of the Miami show. Her hand may be hurt and playing a piano alone may be risky, may cause her pain, or could make her condition worse. I would not expect to see Songbird again until maybe she fully recovers. Carpal tunnel is a bitch. I suffered with it before. It actually never goes away but gets aggravated and comes back.
