Hopefully.
As a point of edification, this is the kind of singing most young women are trying to emulate right now. If we remove our prejudices about whether we personally think this sort of singing is good or bad, and simply follow the money, we can possibly make some guesses about why the older singer and band thought this young woman wasn't up to the task, and why they might have been wrong about that.
A singer with a large enough following to attract the attention of a management company and label might just be doing something with money potential, and might not need Ethel Merman or Mariah Carey to show them the light.
But again, we're all just speculating.
