I'm a big fan of GT.

How do we take advantage of the scales we learn from the many scales lessons in GT to play songs that we are trying to learn? For example, I've been working on Bad Moon Rising taught by Mike Olekshy. I don't see how knowing scales helps me in playing that song. The same question goes for exercises on other skills. It would be nice if the scales exercise lessons could include examples and/or be tied to songs that the knowledge of scales helps us to play. (I hope my question is clear.)
