Danish Crown Princess Mary and her children Prince Christian, Princess Isabella and Prince Vincent attended the premiere of the musical "Peter Pan" at the Glass Hall Theatre in Tivoli. The musical is based on J. M. Barrie's 1904 play Peter Pan and his novelization of it in 1911, Peter and Wen. The award-winning stage talents are bringing characters such as Peter, Wendy and Captain Klo to life in the completely newly written musical.
