fcontent[2]="&quot;Hi Andy, I travel (a lot) with the Army and have just received your guitar steps book.  It is excellent and just the sort of direct, no nonsense yet still professional, piece of literature that I have been looking for. It has provided the clear explanation of guitar basics that other books simply don't show - maybe they don't know!  I am energised by your style, thanks&quot; <i>G.W.</i>";
