Conductor Sir Antonio Pappano is renowned for being a warm-hearted "people person". But there's one thing that makes his blood run cold: when he hears opera being accused of being an art form that's only for a wealthy elite. "I get very offended by people who say we're elitist," he says passionately in a new documentary. This is "a misconception that totally distorts the image of opera," he adds. "The fact of the matter is, it's harder to get into a football game in London than it is to get into the [Royal] Opera House."

This allusion to the beautiful game is not a frivolous one. When Pappano  became music director at the Royal Opera House, Covent Garden (ROH) in 2002, he spoke of his love for popular music by stars such as Frank Sinatra, Tony Bennett, Oscar Peterson, Joni Mitchell, and for musicals. "I like football too," he added. "Does that mean you can't like opera?"
