There really isn't anything new here. When I was teaching guitar I'd tell the students after you learn the basic techniques I will divided the lesson in half, half for continuing out of the book and half for having fun. If ignoring the book learning then the fun stuff will stop. My lessons were not a strictly go from book 1 to book 2 etc. Students learned more advanced techniques more easily when playing songs that they want to play. Learning fun stuff started early in the lessons to get the student motivated. Note that all of the fun stuff was in notation that was modified to the students skill level.

I have had great success with this method and so did the other guitar teacher I was sharing students when we both worked at a music store together. YMMV
