I'm not afraid to say that I think Band Aid was diabolical. Or to say that I think Bob Geldof is a nauseating character.
Despite strong, sinewy songs, like their masterstroke, "Elephant's Graveyard", the Rats commercial fortunes nosedived in the early 80's. It took an unforeseeable turn of events to brand Bob Geldof onto the world's consciousness.
That era-defining change was of course the combination of the 1984 Band-Aid single "Do They Know it's Christmas" and the follow-up Live Aid concerts to raise money for Ethiopan famine. Critics, from Moz (see above) to Chumbawamba to that guy you knew who said that the famine was just population re-adjustment, often zeroed in on "Saint Bob" and his"punk diplomacy". But say what you will about the the man, if punk rock really was supposed to change the world, he's the person with the best claim to have done so. And plus the tunes always rocked.
