Problem: I am anxiously awaiting the arrival of my CD. I was at the concert in Atlanta and was mesmerized during the entire show. It was so surreal..to be in the company of Barbra and Il Divo. I know the CD will be great. It will be the first thing loaded in my car. And, it will probably stay in there for quite a while. There is and will be no other Barbra. I only wish she would tour more often.
Solution: Positive
