On Friday's show, we spoke with Academy award-winning filmmaker Jonathan Demme about his new Neil Young concert documentary, "Neil Young Trunk Show". He's the same man who directed The Talking Heads' performance doc, "Stop Making Sense", a film considered by many to be the greatest concert movie ever made. Few concert movies make it in to theatres, let alone become cultural touchstones like "Woodstock" or "Gimme Shelter". What are your favourite concert films? What does a concert film need in order to be great? Give us your thoughts.
