54 years after she first lit up the lives of the Banks family - not to mention cinema-goers the world over - everyone's favourite nanny is back.

Mary Poppins Returns sees Emily Blunt in the title role, reunited with the household in the wake of a tragedy three decades after events of the original.

It's directed by Rob Marshall, and we're delighted to say that Rob is our guest on this festive edition of Soundtracking - the weekly podcast about film and television music.

Remaining true to the spirit and tone of the 1964 movie, Mary Poppins Returns is a love letter to London, Walt Disney, animation and, of course, classic silver screen musicals.

The score and songs were composed by Marc Shaiman, with lyrics from fellow Broadway legend Scott Wittman, and we also reflect at length upon the Sherman brothers' classics of the original.
