We went to Twilight at Taronga on 24 Feb 2007. It was starring the Beatnix.
They were FABulous :) Very Beatlely! We hadn't seen them in action before but they had us up and dancing to Twist and Shout and Hey Jude!
Some more obscure hits (to my uneducated ears) were played too.
The rain made for interesting hiding spots whilst still trying to be able to see and keep within our "space" and not obstructing other people's view (with our umbrellas). We also had a couple of friends in lovely ponchos.
The concert was very wet, but it just added to the atmosphere. Good company and good music isn't diluted by a little bit of rain and an amazing light show (lightning over the city -- the view from Taronga is amazing!)
