The classic musical Guys & Dolls premiered on Broadway in 1950, winning five Tony awards including Best Musical. Frank Loesser wrote the music and lyrics, and Jo Swerling the book, rewritten by Abe Burrows. Swerling, among others, co-wrote It’s a Wonderful Life, as well as other screenplays. He just wasn’t fluent in Runyonese. Huh? Wildly popular journalist and short-story writer Damon Runyon infused real street dialects with polite, roundabout expressions for comic effect.
