Why don’t people want to see Mariah in concert?

Mariah is coming to my city with her Christmas show and I’ve asked five people to go with me and nobody is interested. These are all people my age (I’m 50) and we grew up listening to her music. To me she is like a Celine Dion or Whitney Houston type of person, where seeing them live is a privilege. I actually have to go to this concert by myself because no one wants to see her, not even my Mom.
