Finally, some honest level headed recollection to this head scratching & presumptuous thread. As Johnny Stew acknowledges, The only producer Stevie really didn't like or get along with was Glyn Johns, which most likely was also exacerbated by Stevie's climaxing klonopin condition. And in the end, it was Jimmy who could no longer work with Stevie to finish RAL because of her heightening coke addition, ego & personal demons.
Since Stevie has been sober, she has worked successfully with many producers including; Don Was ("Somebody Stand By Me"), Pierre Marchand, John Shanks, David Kahane, Sheryl Crow, Glen Ballard & David Stewart to achieve the most cohesive solo recordings of her career since the early 80's.
Perhap's the intent of this thread was to dream about producers we as fans would love to see Stevie work with in the future

I personally would love her to work with a younger producer like Mark Ronson (that could be really interesting) or Jon Brion, or keep things old school with T Bone Burnett, or do another round with Jimmy Iovine as executive producer. But ultimately I'd be satisfied to see her work with Dave Stewart again. Their work together was creatively successful, satisfying & consistent, while retaining the perfect amount of classic Stevie-ness.
