Irving Berlin’s enduring classic, Let's Face the Music and Dance is celebrated by those for whom it has a special significance.

It was written in 1932 as a dance number for the film ‘Follow the Fleet’ starring Fred Astaire and Ginger Rogers.

Since then it has taken on a life of its own, being recorded by hundreds of artists including Diane Krall, Shirley Bassey, Frank Sinatra, Vera Lynn, Ella Fitzgerald and Matt Munroe.

For Sir John Mortimer's widow, Penny, it conjures up the very essence of her husband, who loved life, romance and dancing - even though he was no Fred Astaire, a fact he always deeply regretted.

Lawrence Bergreen, Berlin's biographer and academic Morris Dickstein explain why this song has such a unique place in popular culture.

Cabaret singer and composer, Kit Hesketh Harvey explains why the melody continues to haunt us.

We hear from the bride and groom who decided to dance down the aisle to it after their wedding and the redundant welder for whom the song will be forever associated with the demise of our ship building industry.

An insurance executive recalls how the song became central to their advertising campaign, bringing success to the firm and also placing Nat King Cole's version back in the charts nearly 60 years after it was written.
