Good write up and good to know... I stand corrected. And admit to not visiting, or not in a very long while, any of the sites you mentioned. My thoughts more were about the legion of YouTube sites that put up song lessons. We could hope that I'm wrong about those, as well.
Nice to know about Spooky too. That's one of those second decade songs of R&R/Top 40 I was talking about in my yesterday's post above. 😀 GT published the lesson in August of last year and it was followed up the next month with another Atlanta Rhythm Section tune. How did that August date match up with your request?
They used to have a upcoming song list that would show what songs were coming in the next few months. I'm sure I'm not alone in saying they need to bring it back.
