Aly on the right, AJ on the left. Aly is about 17, AJ is about 15. These girls gave a great show. They really did. They interacted with the audience a lot, had tons of energy, tons of confidence, lots of smiles and thank yous, told the audience what the songs were about, they're quite talented musicians, and they didn't do any crappy dancing like Britney Spears. I have to admit, I was very impressed. Even though I only went for Gillian, it was one of the best shows I've ever been to.
