You'll might actually find this site pretty much to your liking.
A good majority of members here are old fogeys, including the instructors and a lot of the forum members.

We tend to use groovy words like "dude" etc... but overall, I think according to our site specs recently, a lot of our members are people like yourself who are getting back into guitar after many years.

What can I say... there's no obligation here... just try signing up for a month and browse around the instructors & see if there's anything you like.
Most of us have 20+ years of experience and are happy to help if you don't understand something. If you don't find the site to your liking, you're free to cancel at any time :)
