I was talking with my mom a few weeks ago. I mentioned that I had recently heard “You’re So Vain” for the first time and it was agreed upon that the only people who listen to an usually high percentage of ’70s singer-songwriters are boomers who listened to it in high school or college. To my mom, Carly Simon is as big as Elton John but that genre is aging as well as 101 Strings/Jackie Gleason across the generations, commercially speaking.
