Query: Not worth it!

All of the information that is in this book can be had by googling "bluegrass jamming" and then spend 30 minutes reading.Also, I go to bluegrass jams all of the time and never hear half of these songs played. This book seems to me to have been quickly thrown together and titled to attract people brand new to jamming.I'll save you the time....here's what the book says: Learn to look at a guitar players hand to recognize chord changes and don't be rude in a jam. The rest is just teaching you (very weak) note for note versions of some tunes that you can, and should, learn by ear.
