Last thing about Live 8, honestly

When Bob did his "don't say this doesn't affect things" big set-piece by bringing on Birhan Woldu from the ending to the famous Canadian Ethiopia film I wondered why I knew what was about to happen. This, I now realise, was because Geldof did exactly the same at the Band Aid 20 press call. Also, not to denigrate what was an incredibly powerful moment, how did Live Aid make a difference to her life as claimed given the footage was shot nine months previously and the crew knew she'd survived then? (note in that link the reporter's bafflement at the Sun 'finding' her two years after he had)
