Here's my interview with Sir Paul McCartney about the score that he's composed for the New York City Ballet's Ocean Kingdom.

Ahead of the production's gala premiere, the former Beatle admitted to not having been an afficianado of ballet before getting involved in the project.

He said: "I don't know much about ballet... I kind of know Swan Lake and The Nutcracker."

His daughter, Stella, designed the dancers' costumes for the production, in the first collaboration between the two McCartneys.
