It’s different for women performers, though. As I say, their fanbase eventually becomes old gay men.
The only exceptions are heavier rock performers, like Pat Benatar.
Tina Turner kept going until her body just couldn’t. Same with Aretha Franklin. Celine. Melissa Etheridge is still rolling. Plenty of women just keep on trucking. Even if it’s just old gay men in the audience, which it isn’t, so what, old gay men spend money, great audience to have.
