Clover Lighter 'life lovers' by Grey London

The ad was filmed during a live performance at a food festival. It will air on TV and in cinemas, and will be supported by outdoor and experiential work, with a custom-designed "Yes You Can" van travelling around the country.

Visitors to the Clover Lighter fan page on Facebook can meet the members of the choir and enter a competition.

The work was created by Vicky Maguire and Jay Marlow, and directed by Jake Nava through Cherry.
