In 1999, Frank became the first American composer in twenty-two years to have three shows running simultaneously on Broadway: Jekyll & Hyde (written with Leslie Bricusse), which received two Tony nominations; The Scarlet Pimpernel (written with Nan Knighton), which received four Tony nominations; and The Civil War (written with Jack Murphy & Gregory Boyd), which received two Tony nominations. These shows continue to be seen in productions around the country and throughout the world. Frank also wrote additional songs for Broadway's Victor/Victoria (written with Leslie Bricusse) and was recently represented on Broadway by Dracula: The Musical (written with Don Black & Christopher Hampton). He was also a Producer and Co-Creator for Harlem Song, the first open-ended theatrical run at the famed Apollo Theater in Harlem, NY.

Jekyll & Hyde holds the distinction of being the first new American musical to have two internationally released concept recordings of the score: Highlights from Jekyll & Hyde and Jekyll & Hyde: The Complete Work. Songs from the show such as "Someone Like You," "A New Life," and "This Is The Moment" have been performed worldwide and have been featured at the Olympics, the Super Bowl, the World Series, the WNBA Championship, Miss America Pageants, the 1996 Democratic National Convention, and the Inauguration of President Clinton (sung by Jennifer Holliday). The Broadway cast recording was released in July of 1997 and received a Grammy nomination that year. The Broadway production of Jekyll & Hyde was the longest running show in the history of the Plymouth Theater. The show has seen three major tours and hundreds of regional productions in the United States and Canada. Over 35 international productions have also been seen in such countries as Germany, Austria, Spain, Hungary, Japan, Sweden, Belgium, the Netherlands, Denmark, the United Kingdom, and Australia. There have now been ten international recordings of Jekyll & Hyde in six different languages.

The Scarlet Pimpernel played at both the Minskoff Theatre and the Neil Simon Theatre on Broadway. The show has been seen on two tours of the United States and Canada, and in such countries as Finland, Mexico, the United Kingdom, Ireland, Australia, New Zealand, the Netherlands, Germany, Denmark, and Malta. The show's score has yielded its own Top 40 Adult Contemporary Hit with the song "You Are My Home," a duet recorded by Peabo Bryson & Linda Eder. The Broadway cast recording was released in February of 1998, and a new album entitled Encore! was released in November 1999. A German-language recording was released in 2003.

Frank has produced two star-studded concept albums of The Civil War: The Nashville Sessions and The Complete Work (a two-disc album). These feature such artists as Hootie & The Blowfish, Blues Traveler, Trisha Yearwood, Travis Tritt, Dr. John, and Betty Buckley, among others. Following its Broadway production, the show was seen on a two-year national tour that featured John Schneider, Larry Gatlin, and BeBe Winans.
