The Yeomen of the Guard.

Taking place in the Tower of London during the reign of King Henry VIII, this classic Gilbert & Sullivan operetta is one of their darkest and most sophisticated. Colonel Fairfax is wrongly accused of sorcery and sentenced to death within the hour. He hatches a plan to avoid letting his estate fall into the hands of his scheming cousin (incidentally, his accuser) by secretly marrying Elsie Maynard, a strolling singer. She agrees to be blindfolded during the ceremony and expects to be a wealthy widow upon Fairfax's imminent demise, leaving her free to marry her lover, the jester, Jack Point. However, Fairfax miraculously escapes his fate and chaos ensues.
