This hay bale performance is intended to help these Friesian cows produce extra special cream that will eventually be made into gelato. It's a part of the recipe! My favorite is the farmer's face:

Acclaimed Italian Tenor Marcello Bedoni gives a performance to a field of Friesian cows in Lancashire to recreate the original family recipe for Antonio Federici's ice cream which stipulated that opera should be sung to the milk producing cows.
