At one point in Joe Dunlop’s Boy's Own adventure-style dramatisation of the events leading up to Live Aid, concert promoter Harvey Goldsmith asked Bob Geldof: “Why are you doing it, that’s the question?” I’ve interviewed Geldof on a number of occasions and there’s no doubting either the sincerity or enduring nature of his commitment to Band Aid. I’m not sure, however, that I or anyone else, and certainly not this film, has ever quite got to the bottom of Goldsmith's question. Why Geldof? Why Ethiopia? And why couldn't he let go?
