Marvin Gaye - 'What's Happening Brother"

I was listening to What's Going On the other night - it's still one of my all-time favorite albums. As the Wiki entry explains, "The album is told from the point of view of a Vietnam War veteran returning to the country he had been fighting for, and seeing nothing but injustice, suffering and hatred." (Marvin's brother served in Vietnam.) The YouTube description for this video says, "A visual montage taken from photos in the SOUL SOLDIERS exhibit and the film directed by Chris Ivey at the Heinz History Center."
