A Black Disc with lights going around

Around 20:15 PM, April, 1975, Mildura a country town, night had fallen, a clear night sky.
I love the night sky.
On foot , returning from a short  errand.
A final look at the night sky, turned around, and there it was, a large  black disc with  lights going round and round,   just sitting there in the sky, low enough to land,  I reckon half a mile up maybe less,  hovering,  I thought it was going to land, it just sat there.
Brass band music  was coming from a nearby sports ground, the rehearsals of a  marching girls team.
I strained to hear the drone of  a helicopter, it was low enough  to lift the dirt away from the ground as a chopper does, no, not that.
I heard our  neighbour come from his house , and made his way towards me, not noticing what was in the sky,  when I  stopped him and proceeded to ask   him , pointing to the object in the sky.  ``what is   this?  so that I’m not dreaming``, he turned around, looked and said  holy ``----- its a UFO ``.
We  stood there for sometime, before my neighbour left , as he  mentioned that  he had things to do in Mr --- `s  home, two houses from mine.
Being 16 on the street after dark ,I returned home quickly, to find my mother stressed over the new TV not working, I said I had just seen a UFO to her disbelief, a member of the family ran from the house to catch a glimpse of it and returned to say that it had gone.
