Spice Girls line up for Live Aid

The Sun reports that The Spice Girls are to take part in 'Live Aid 2', by which I think they must mean Live 8, because hasn't Bob Geldof been strenuously denying that there is going to be a Live Aid 2? Anyway, The Sun says that the Spice Girls will reform for whatever event actually happens on 2 Jul and quotes a source as saying "The dance routines may be a bit rusty but they'll put on a great show." I'll believe it when I hear it from the Live Aid Foundation. Or the Band Aid Trust. Whichever one it is.
