U2 upped sticks with much of its operation when the artists' tax exemption was capped in Ireland, some years back.
Interestingly, Bono once defended the very person who introduced the exemption, Charlie Haughey - just when some sections of the Irish public belatedly realised what a corrupt shyster the man was.
But Bono has been known to rub shoulders with some very unsavoury characters, in his endless quest for ego-massaging publicity... he's Mother Teresa with silly yellow shades. (See book cover.) And just as ineffective, to put it - erm - charitably.
Harry Browne has a book out on Mr Vox which, judging by initial reviews, is well worth a read. The Irish Times reported that friend of the Hewsons (aka Mrs and Mrs Bono Vox), and fellow look-at-me-I'm-doing-good-deeds merchant, Adi Roche, has said that people shouldn't buy the tome.
And what better recommendation could you get than that?
