@Skematica Yeah, great sound. I remember going to roller-discos as a youngster, when "Cars" was in the charts. Funky moves on quad skates might have been done to that. Good times.
@Skematica I only recently threw out my old cassettes! Various charts recorded from 1976. Tina Charles (Dr Love), David Soul, etc. One was around the time of this [officialcharts.com] chart.
