   'Viz' fizz wanes as readers bottom out  THE GUEST list for
the Viz party on Thursday says it all. They've got Ray Davies of
the Kinks, a couple of blokes from Aerosmith, Lionel Blair, and
one of the Bay City Rollers; and Suzanne Dando is a possible.
Usefully, the back of the invitation gives ordinary guests
etiquette tips: 'DO NOT stare at the celebrities. DO pretend not
to recognise them.' But there are no young celebs at all. Viz,
the 'comic for older boys and girls', has become the comic for
thirtysomething boys and girls.  'We don't want to write about
Michael Jackson and monkeys,' says Chris Donald, its editor.
'Our references are to things that were on the telly in the
Seventies - Mud, Sweet and John Noakes. The 14-year-olds with
baseball caps turned round who listen to raves haven't heard of
John Noakes. So they don't want to read Viz.'  That means Viz's
circulation is falling. At the end of the Eighties Viz, founded
in 1979, was selling 1.2 million copies. Its last audited
circulation was 713,000.
