FLASH SPECIAL: What Are You Doing New Year's Day?

Today we are taking a look at a sensational seasonal showstopper by one of Broadway's best songwriters, Frank Loesser, performed by a line-up of legendary greats sure to start your 2014 off on the right foot - and left!

Of note, the song was originally not composed for any project in particular, theatrical or otherwise, though it nevertheless reached #9 in its first R&B single version as recorded by The Orioles in that same year.

Subsequently, Dante & The Evergreens and Nancy Wilson also found some success with single versions of the song, as well, though its iconography truly lives on through its many, many covers - old and new. Indeed, since its inception, the song has been covered by a vast selection of artists as diverse as Ella Fitzgerald, Barbra Streisand, Eydie Gorme, Bette Midler, Diana Krall, Patti LaBelle, Liz Callaway, Johnny Mathis, Harry Connick Jr., Rod Stewart, Barry Manilow and The Carpenters, among the hundreds of cover versions created over the years. As a matter of fact, since 2011, nearly 14 million people have viewed a video by Zooey Deschanel and Joseph Gordon-Levitt crooning it alone!

SMASH star Katharine McPhee makes the classic her own.

Rufus Wainwright spins the selection in his unique way.
