I grew up on much of the Beach Boys music. And yes,, Brian was the genius behind many of the songs & arrangements. We've truly lost a great one. Yet,, we can easily reflect back,, listen to the songs, and know it'll be timeless & he won't be forgotten.
Yes,, he may have had his demons, but so many people do. Successful & not do successful.
So I'll choose to remember the great stuff he did,, feel compassion for his issues,, and sing & dance to the music!
RIP Brian,, and "Thanks for the memories!"
