She did a gig here in the UK some years ago and the auditorium wasn't very full.
She refused to perform.
[The same thing happened to Kiki Dee at a smaller venue, and Kiki came on stage and down the mic asked everyone to come and sit together at the front to make it seem full and still did her show.]
So, to me, Dionne came over as a bit grand and it made me dislike her.
And I felt that her Christian beliefs might be a bit of a 'front.'
And although I think it's great to believe that the Lord will provide etc, but as far as I know, He doesn't do your accounts and pay your tax bill for you.
