Super info, thanx. It would have been a memorable day in the city, but alas I was probably in Mildura waiting for year 12 to start. My target is to try and discern the Fhone amplifier model used on the rear of the truck - perhaps a nerdy aim, but the journey is full of memorable aspects, given I like many grew up with only Countdown providing video of bands, and the local radio station (3MA) was not very progressive, and the stratosphere had to be in good shape to pick-up 2JJ.

I was able to download the City Square video, and that has much better footage of the amps - so I have succeeded in getting what I wanted. Ta.
