Query: Groban at the Greek is GREAT!

I LOVED this CD/DVD!!! The music is superb, the performance was polished and professional, and the bonus footage at the end is terrific! Not only is Josh Groban an accomplished vocalist, but his bits on the piano and the drums were very entertaining. His choice of songs shows versatility and a sound grasp of what his audience likes. I can't wait until he puts together a Christmas album!
