This was published in a collection of Duarte arrangements, Classic Jerome Kern, Chappell Music 1984. I see that a couple of very pricey copies are available at Amazon. If you google "Duarte Classic Jerome Kern" you'll also find it online. In addition, Duarte published a set of Gershwin arrangements in Classic George Gershwin, Chappell Music 1984. It's also online, but I didn't find any copies for sale at the moment. Happy hunting.
