As a rule, New Year's Eve is at its best when it has the aesthetic of a 1940s jazz club. No one knows that better than American Songbook expert Michael Feinstein, who, on December 31, 2014, hosted an old-fashioned black tie New Year's Eve at the Rainbow Room.

The bill was stacked with Broadway stars, but none so shiny as Tony winner Kelli O'Hara (The King and I) and Aaron Tveit (Next to Normal), who dueted on the Burton Lane and Ralph Freed song "How About You?" It was originally performed by Judy Garland and Mickey Rooney in the 1941 film Babes on Broadway — but O'Hara and Tveit did their predecessors proud with a version of the song that blends updated lyrics with Golden Age class. And isn't that really the combination we're all striving for in the New Year?
