Let me be blunt....(pun somewhat intended.....) perhaps not as eloquently as Mr. Mallette.....
I am over 60, barely
I am not an "old geezer" as you so lovingly refer to "us"
"Rock and Roll", "Jazz", "Blues", etc, are stunningly general terms that you seem to use so very casually
I love music. I don't live my life (or criticize others), via the lyrics in any song
I'm not a low life loser because I enjoyed, (and still do) the music of those that had drug problems, sex problems, alcohol problems. There are many artists that I enjoy that don't (at least publicly) have those issues.
Your "chapters" and arguments are steeped in "we", "us", "the world", "people".....etc, etc, etc. Perhaps you need to look inward, and speak of YOU. Please don't assume anything of me. Thank you.
