Query: Great All-Around Harp Book and CD

I found this book quite extraordinary in helping me to play the harmonica better. The CD was well crafted. The book was all-around fun and accessible. Reading some of the other reviews, I can't help but wonder about some people. Yes, the book revolves around a silly series of stories, but, man, that's not only part of the fun, it also helps you to remember what's going on. I thought it was very well thought out, and kudos to the author for breaking the mold and being inventive!
