You are on the right track, finding someone to play music with!! I really don't know much about the songs that are taught on GT. That was not what I came here looking for. However I do know that finding people to play music with, is proably the best way to sustain your long term interest in playing guitar. Loosing inerita is the biggest reason people stop playing guitar. Musical partners are a great antidote for that pit fall. Nobody wants to let their friends down...especially when playing muisic with them is so much fun. I think that is called the carrot AND the stick approach. It works!

I have no doubt that people will come on here soon and provide you with directions to finding material that you and your neighbor can play together. I know that my musical journey would have never progressed beyond the sore fingers part, without having musical friends. Music is a social practice. We all get by "with a little help from our friends".
