Hello Mark,
A fellow Baby Boomer here. Welcome. For now, forget about reading the seemingly inexplicable notes on the site's standard notation. What you want to do right away is complete a relatively quick guitar tabs tutorial. "Tabs" refers to the diagram of six guitar strings with numbers and squiggles that's positioned immediately below the standard notation anywhere on the site. This will fast become your best friend in here and will put you on the road to playing those Pink Floyd tunes, including the faster ones.
And watch out for Bill. As you can tell from his avatar, he's capable of swallowing a man whole without dropping either his guitar or his cigar 😂

Hey Miss Sascha, I wanted to get back with you and thank you for suggesting other instructors- specifically Miss Lisa. Not to say anything negative regarding Anders because there is no negative. As discussed, it's simply a matter of different instructors at different times for different reasons. I've been studiously working Lisa's sub-elemental lessons. And sure, some are truly elemental. However, I like it. It's like wiping the slate clean, saying you're a total know nothing student and going from there. Most importantly, she resolved a big chunk of my left hand problem. So, bottom line- again- thank you.
Mark
