Focus on Trade usually relies on the written word for analysis, but one of our readers, Professor Bill Carroll (University of Victoria, Canada) this week released his second political music video, titled, “So Said Tony Hayward”. Carroll says the song practically “wrote itself” drawing on the wealth of material that gushed from the mouth of BP’s former CEO. But the song is also a black reminder of the scale of the disaster and the gross corporate culpability.  You can listen to Bill Carroll on youtube:  http://www.youtube.com/watch?v=4li0MzzRXMU
