LONDON (Reuters) - They may have been casting off the yoke of British rule, but the cast of Broadway smash ?Hamilton? nonetheless received a rapturous reception from a star-studded, 1,500-strong audience at the show?s official opening night in London on Thursday. The show, created by Lin-Manuel Miranda, is an unconventional take on the life of Alexander Hamilton, one of the founding fathers of the United States, featuring a racially diverse cast and a hip-hop-inflected score.
