The book is by Jerome Weidman and George Abbott, drawn substantially from the 1955 volume Life with Fiorello by Ernest Cuneo, with lyrics by Sheldon Harnick, and music by Jerry Bock.

It won the three major theatre awards - Tony Award (shared with The Sound of Music), the New York Drama Critics Circle award, and the Pulitzer Prize for Drama. It is one of only ten musicals to win the latter award. As a side note Mr. DaSilva was blacklisted for many years by Hollywood In 1947, his career was threatened when the House Un-American Activities Committee (HUAC) began its investigation into alleged Communist influence of Hollywood. Actor Robert Taylor, called as a "friendly witness", accused many of his fellow actors and writers of either being communists or having communist sympathies. When questioned about da Silva, Taylor said, "I can name a few who seem to sort of disrupt things once in a while. Whether or not they are communists I don't know. One chap we have currently, I think is Howard da Silva. He always seems to have something to say at the wrong time."
