This is the official info on the show and a clarification of the stuff I said on my post above, from its Wikipedia page:
"A workshop was performed in November 2007, featuring Harry Connick Jr. and Erin Dilly. At that time, the show was titled Heaven on Earth. The musical was first scheduled to debut at the Colonial Theatre in Boston, running from December 16, 2008 through January 11, 2009. The production was expected to open on Broadway in Spring 2009. The production announced that Harry Connick, Jr. would star as a "Long Island playboy". Scenic design would be by Derek McLane and lighting design by Kenneth Posner, music arranger/supervisor was Rob Fisher, and costume design was by Martin Pakledinaz.
On June 2, 2008, it was announced that Kathleen Marshall, who was formerly announced as director and choreographer, was no longer with the project. According to a statement made by Broadway Across America, the previous producing team "has disbanded due to irreconcilable differences", and Broadway Across America has assumed the lead producing role.
According to The New York Post, it was triggered by a feud between Ann Marie Wilkins (Connick's manager), and Scott Landis (Connick's agent and Marshall's boyfriend). On July 25, 2008, it was announced that the musical was "officially postponed", as they needed more time to work out the details, after the change of producing team.
Connick mentioned in an interview on The Today Show on MSNBC on January 29, 2009, that the Broadway production was to be directed by George Wolfe. It was then announced in the June 2010 issue of Playbill magazine that Harry Connick, Jr. left the project, citing his own personal feud with Kathleen Marshall.
A new reading was scheduled for October 8, 2010, starring Matthew Broderick and Sutton Foster, with Kathleen Marshall directing and Scott Landis producing. Broderick has been announced as starring in the musical, which is slated to open on Broadway in Spring 2012 under the direction of Marshall, who will also choreograph."
