Content:  The video for "Don't Worry Be Happy" was filmed in Sydney, and was released to iTunes and other digital download sites on 21 November 2011. In the video Sebastian is seen as a businessman having a difficult day. He pours curdled milk over his breakfast cereal, steps out of his apartment building into a rain shower, and his day at the office is shown to be stressful. He walks down to the beach at lunch time appearing very disgruntled. As he begins to eat he looks across at the next bench and notices a sad obviously ill young girl sitting in a wheelchair next to her father. The businessman appears to come to the realisation that his day isn't as bad as it seemed. He puts down his food and runs into the ocean fully clothed, falling backwards into the water with a smile. The young girl breaks into a smile as well.
