$300M each - even adjusted for inflation, I doubt Page or Plant ever earned that much from all of their ‘70s tours combined. Baby boomer nostalgia rock is obviously profitable - can newer acts like Justin Timberlake or Taylor Swift command fees like that?
Maybe in the 2050s, there will be a billion-dollar Justin Bieber concert.

I don’t know but Swift can fill Giants stadium. That ain’t bad. It seems to me that there aren’t as many acts that can do that as there once were.
