"Dreamers", by Supertramp. I haven't heard this song for many a long year, but when I was 11 or 12 years old I listened to it over and over, thanks to my "exotic" and "sophisticated" Melbourne cousins. (It has actually aged pretty well. Some of their other songs haven't.) I wonder if my fascination with this song back then has something to do with my present obsession with the sound of the electric piano.
