Walter Afanasieff or Robby Buchanan? Which one played Keyboards on "A Whole

[babyteen]

When I was listening to the Descriptive Video version of Aladdin, during the end credits, the description narrator said that "A Whole New World" performed by Peabo Bryson and Regina Bell was produced by Walter Afanasieff and Robby Buchanan. I know that both Walter and Robby are keyboard players, but which one played keyboards on "A Whole New World"? And, how would I contact either of them, since I want to find out exactly what kind of keyboard it was that was played on that version of the song. I know it was some kind of electric piano sound, but which kind I'm not sure.
