As regards the Grammys, all she had to do was send either Rhonda, Tracee or Evan to say thank you very much and goodbye. I think the Supremes legacy deserved at least that much consideration.
Regardless of any personal feelings towards the Supremes, Diana is first and foremost a business woman. She will never stop performing those songs because she understands that’s what puts backsides on seats. She’s also savvy enough to realise that despite a glittering solo career, her tenure with the Supremes is what she will always be best remembered for.
