Ah, Thanks ever so much Kevin D. (That's fair made my Sunday morning!)
Pre Caroline (60s) it was rare to hear French (or any foreign language) music at all on the radio. Caroline did include quite a lot, so we have them to thank for raising our musical horizons in linguistic terms, as well as genres. But since the 70s or so, Eurovision is the only place we see or hear any. RNI did a lot to raise our horizons, and Caroline did for a short while in the 80s, but this last ¼ century we are again starved of international, or even near continental music.
A pity that.
