When it comes to television, Norman Lear could write his very own “How to Succeed” guidebook: The legendary producer created timeless sitcoms such as All in the Family, Sanford and Son, Maude, The Jeffersons and One Day at a Time.

After the performance, Lear and Griffin headed backstage at the Al Hirschfeld Theatre to congratulate Broadway’s newest musical star, Daniel Radcliffe.
