There's only so long you can spend in a pub discussing the on-set problems during the shoot of Apocalypse Now / which Martin Amis novel is the worst / the small print in the FT. If Bono's hair provides a lighthearted means into a spot of lighthearted and frivolous banter about nothing in particular with a few laughs thrown in, just to pass the time, then I'm all for it. Slebrity in nothing new, and half the new ones are no better or worse than half the old ones from the last few millenia: Gladiators (famous for killing people), Good-looking people (natural ability to be good-looking), Murderers (killing people), Saints (being fictitious. getting killed), Soldiers (killing people), Footballers (natural ability to kick ball), Royalty (being born into royalty / killing people).
