Becoming John Adams in 1776

William took on one of his most demanding roles as John Adams in the Broadway musical 1776.

Reflecting on the experience, he penned on his website: "I had nine songs and two were solos. I never left the stage. I became the driving force in a successful Broadway musical, something I never thought possible.”

He later reprised the role in the 1972 film and the 1976 miniseries The Adams Chronicles.
