New father Sir Elton John is working on a Broadway musical aimed at children.

The singer and his partner David Furnish became parents to son Elijah, a sibling for two-year-old Zachary, earlier this month (Jan13), and 2013 is shaping up to be a busy year for the couple.

In an interview with Britain's Hello! magazine, Furnish reveals, "Later this year we begin filming Rocketman, a biopic of Elton's early life. Towards the end of the year we are also planning to open a children's musical on Broadway."

No further details of the project are known, but the singer will be adding to an impressive stage resume - he has previously composed the score for Billy Elliot the Musical and created tracks for Disney movie The Lion King, which was later adapted into a theatre show.
