In the 1990s, he also produced several albums for Sony Classical, with conductor John Williams and The Boston Pops, including "The Star Wars Trilogy" (Skywalker Orchestra); "The Spielberg-Williams Collaboration"; "I Love a Parade"; "Kismet", starring Samuel Ramey, Jerry Hadley, Dom DeLuise, Ruth Ann Swenson and Julia Migenes; and "The Green Album", among others.
