Ok, let me try to be a bit more specific. As far as their location, I too am confused as to whether they are Aussie, or New Zealand. I have heard both try to claim them.
Neil is the shorter one, dark hair. IMHO adorable!! He is the Crowded House frontman.
Tim is taller, with grey hair. Although he was with CH off and on through the years, he is really more known for his Split Enz career. There is rumored to be quite the sibling rivalry that kicks in from time to time, which would explain their sporadic careers together.
I hate that I missed Liam on Letterman, and no, he did not have anyone with him, so I will have to check out the girl you were talking about. All I can tell you about Liam, is that he showed up on stage in Atlanta - no body knew who the heck he was - and when his set was done the crowd was on it's feet!! He came back for an encore. How many times do you see that happen with an opener?
There is a rumor he is coming to the Attic!!
I'm very excited, but don't want to count my chickens just yet.
