Happy Birthday, Stephen Sondheim Broadway is dark because of the virus, but that doesn't need to stop us from celebrating the 90th birthday of Broadway's best living composer and lyricist—and one of the best in the history of Broadway, Stephen Sondheim. His 90th birthday is Sunday. We're listening back to our interview from 2010, which we recorded on the occasion of his 80th birthday. He wrote the songs for 'Sweeney Todd,' 'Follies,' 'Into the Woods,' 'Sunday in the Park with George' and 'Merrily We Roll Along.' Revivals of two of his shows had to go dark because of the virus: 'West Side Story,' for which he wrote the lyrics, and 'Company.'
