Not having sen the show, but having known what was cooking for some time now, I don't think they are in fact looking for a new Michael.
As Little river band is mentioned here, and mindefull of the fact someone from Creedance Clearwater revival once quoted that band t0o be the best harmony group in tyhe word at the time, John Farhnam revived his flagging carreer during his stint asa lead vox for them enough that he became the absolute top of down under vocalists popular wise.
S o. Whatever the aims or outcome 0of this, I am sure some will get a bit more of a chance at geting whatever they are pedasling out of the venture.
This little bloke just penned one and, because I have a little leg in the dor via my medai stuff, I am sending it to their suits in the hope they can make it the next Australian National song.
They don't want it, i will try Kevein Bloody Wilson on with it.
Just have to include a few naughty words, beer and meat pies with sauce for Kev to do it I am sure.
I'll include the link to this in my e-mail to the INXS camp.
I'm sure they will love it.
Graham
