Query: Delightful!

I am SO glad that I treated myself to this CD! The arrangements are inventive and the vocal harmonies are amazing. Yes, you've heard most of these songs before -- but not like this. Playful, uplifting, beautiful. Not a single loser on the CD. My son, of course, loves "You're a Mean One, Mr. Grinch." I can't quite bring myself to choose a favorite yet.
