We're about the same age and, although I didn't start from scratch, I did re-start after not playing since '76...over a third of a century!
So my story is kind of a blend of your and your brother's stories. Further, my story is highlighted by a very happy and successful time on GT. I'm a great believer in GT...you bring the guitar and time to practice, GT will take of the rest. :)
"It takes a lot of devotion and work, or maybe I should say play, because if you love it, that's what it amounts to. I haven't found any shortcuts, and I've been looking for a long time."
