@Sugar Mouse you appear to know so much Australia/NZ music, I would've assumed you'd lived here for some time lol.
Probably going a bit off track here, but re Jimmy Barnes - he's from my local city. One of the original wild and raucous rock'n'rollers. These days I think he does too much screaming rather than singing for my tastes. But I really liked his work with Cold Chisel. Not sure if you know of them as well, but they had some very well written songs by Don Walker. Jimmy and Ian Moss also did excellent snging together. You might enjoy some of their work.

I checked out Neil and Jimmy's duet version of 'Lola'! Liked the parts where Jimmy was singing in tune with Neil. Then he just can't help himself - he has to go into full rock belt.
That's Jimmy though. He's a 'character'.
Then there's this version of 'Oh Well' with Mick Fleetwood's band. Mick seems to be quite a fan. So yes it's a small world.
