One of the most stressful yet fun experiences I had in Hollywood a quarter century ago was working on a TV special commemorating Arista Records 25th Anniversary and celebrating Clive Davis (lo res video attached). It was a Dick Clark Production, and I'd been hired to be the security coordinator despite having zero experience working security. About an hour into the gig, I was so overwhelmed I was convinced there was going to be a high body count. But the lineup of talent who appeared on the show was amazing. I think I've written here previously about Whitney Houston and the surrounding drama (banned from multiple airlines/airports) that accompanied her, but it's worth noting that the instant she walked onto the stage at the Shrine Auditorium, she was -- as the kids might say -- fire. I snuck my mom and one of her friends into the audience for Barry Manilow's soundcheck (my mom's reaction to seeing one of her favorites performing, "He's so little, you want to put him in your pocket"). Somewhere in my archives, I still have Aretha Franklin's contract to appear on the show. Her demands included her salary paid to her in cash, in a briefcase, in advance or she would not perform.
All of those artists probably would've found their way to success and fame without Clive Davis, but luckily for them they didn't have to.
