Jackson had played the part in this past season's City Center Encores! engagement.
As previously reported, the fall Broadway revival of Finian's Rainbow — the 1947 musical comedy satire by Burton Lane, Fred Saidy and E.Y. Harburg — will play Broadway's St. James Theatre.
The production, an expanded version of the March City Center Encores! concert, will begin previews Oct. 8 with an official opening Oct. 29. Tickets are currently on sale through Jan. 3, 2010, by visiting Telecharge.com.
The cast will also feature Wonderful Town's Kate Baldwin (Sharon) and The Seafarer Tony winner Jim Norton (Finian), who starred in the Encores! run, as well as Young Frankenstein Tony nominee Christopher Fitzgerald as the leprechaun Og and Tony Award winner Chuck Cooper (The Life) as Billboard.
Finian's Rainbow, according to press notes, "tells the story of the Irishman Finian McLonergan and his daughter Sharon who travel to a small Southern town in the mythical state of Missitucky with plans to bury a stolen pot of gold in the shadows of Fort Knox, in the mistaken belief it will grow and multiply. They have been followed from Ireland by the owner of the gold, a leprechaun, who shows up determined to recover his treasure."
The score boasts such tunes as "Look to the Rainbow," "How Are Things in Glocca Morra?," "When I'm Not Near the Girl I Love (I Love the Girl I'm Near)," "Old Devil Moon" and "If This Isn't Love."
The original production of Finian's Rainbow opened at the 46th Street Theatre on Jan. 10, 1947, and played 725 performances. Michael Kidd won a Tony Award for Best Choreography.
