Neil Patrick Harris starred as Bobby, the lead in Sondheim's popular 1970's hit "Company."
If you don’t recognize the composer, surely you know the music.
The award is the superlative award in the arts community and is given by the city of New York for contributing to the arts, according to The New York Times’ ArtsBeat blog.
The medallion will be presented to Sondheim by Mayor Michael Bloomberg and Alec Baldwin at the famous Lincoln Center, where, most recently, a revival of Sondheim’s “Company” was staged, starring Neil Patrick Harris, Stephen Colbert, Christina Hendricks, and Jon Cryer.
Sondheim has also penned musical theater greats like "A Little Night Music," "A Funny Thing Happened on the Way to the Forum," "Sunday in the Park with George," and "Folies."
