Well, since my computer won't read the CD enclosed I don't know what to say. The book looks interesting, I am completer beginner, and have found other free sites on the net regarding playing guitars. The book and CD was given to me as a gift, so I have no idea where it was purchased, probably Amazon. It was a Christmas 2009 gift but it took me until September 2010 to decided to look at it and try it. I have to give it a one star rating out of 5 simply because I can't get the disk to play! What next? There are no web sites to ask for a new CD and it costs about $2 on the net to download the stuff free anyway. In the process another seller has your email address and credit card info and I don't like that idea! OK Steve, maybe if you read this you can contact me and send me a new CD.
