WIKIPEDIA : Lord of the Dance is an Irish musical and dance production that was created, choreographed, produced by Irish-American dancer Michael Flatley, also its star.
Michael Flatley found his first fame starring in Riverdance, but he left the show in 1995 before its debut in London after a disagreement over creative control. Flatley dreamed of putting together a dance show capable of playing in arenas instead of traditional theaters.  He soon began thinking of rhythm patterns and steps for an a capella number. This number would later become "Planet Ireland", the show's finale. The show took 6 months to bring it from conception to the stage. Auditions were held in the SFX City Theatre in Dublin.
