It is a love story titled “Ocean’s Kingdom” and will have its première at the company’s fall gala on Sept. 22, with other performances on dates to be announced next season, Mr. McCartney and company officials said on Wednesday. City Ballet’s ballet master in chief, Peter Martins, will create the choreography.
In its current state the ballet is about 45 to 50 minutes long, has four acts and a cast of about 40 to 45, including 4 or 5 main roles. A composer, John Wilson, is helping with the final orchestration, and the first act is to be played through Thursday at the David H. Koch Theater, the company’s home at Lincoln Center.
The other half of the gala program will consist of George Balanchine’s “Union Jack,” which Mr. Martins said would be a tribute to City Ballet’s new Liverpudlian contributor.
