My question is this: Late Last year I bought the Beginners book and the Blues book. Unfort to my shame I put it down and have not got back to it because I really needed to at this time have lessons with a teacher at first. I just needed that structure, Anyway , I am back. Is there any difference on these books from when I purchased them last year? If there is I am reaqdy to start over on them? Any thoughts would be great; Vinny
