My uncle was a pretty big pop star in the 1960s. His group at one point had a big fanzine, they were household names across the country, over time they had stalkers and weird fans and all that, made movies and albums, had big parties and knew other famous people, pretty much all those things that the OP writes about (circa 50 years later, some of it has changed but not that much).
He could be charismatic and surprisingly eloquent and I could picture him writing a piece like this, if the mood had struck.
He also lost pretty much all the money through mismanagement (several times over), eventually moved out of LA, had a tumultuous family life with numerous spouses and wasn’t around much for his kids, and after his 40s was trapped in a sad cycle of reunion tours because the band still needed the money. The tours still had some level of excitement and crowd enthusiasm, even pretty late in life and I guess he always loved the stage, the performing, all that. But in the end, I kinda felt it seemed like a lonely existence. Hard to form really deep connections when you’re always traveling and often away in your head.
