RATW started as a weekly 1-hour early evening show (Mondays) in 1982, then gradually expanded to run four nights a week in half-hour episodes by 1984. It wound up early in 1985 ahead of the network’s re-branding as SBS.
Host Basia Bonkowski also hosted another music show, Continental Drift, which (i think?) ran late on Saturday nights, though my memory is a bit sketchy on that.
The week’s episodes of RATW were repeated late on Friday nights (at that stage SBS didn’t really sign-on until mid-late afternoon on weekends and it was usually with kids movies/cartoons or soccer/sport)
