Love? Well not that much it seems

So, it’s the late mid-80’s and you’ve not won since 1983.  Luxembourg botched 1984 with Sophie Carle (who could have got in here on her own dubious merits), but you’re following up a third place in the previous year. All you need now is an act with a international pedigree and a recent hit.

Oh… but you’d need a good song!
