I saw my first Broadway musical in 1979: a revival of The King and I starring Yul Brynner and Constance Towers. (REFERENCE ICON) The King and I was a 1950s American stage musical. 1979 was the NEEDS EDITING end of a the decade in which microphones became ubiquitous on Broadway, so I heard a King who captured me not only with his stage presence but with his enveloping voice. Microphones had been around for years, of course, but in the course of the seventies they became universal. Over the course of the following decade, the next wave of amplification came in the form of body mics: big musicals like Les Miserables put a microphone on the person of each and every cast member.
