Wyn Hoop was only 23 years of age when he took part in the Eurovision Song Contest, that took place in London. His entry Bonne nuit ma chérie was a tender lullaby where the singer puts his love to sleep promising he will never forget or leave her.
To me everything is in place in this entry. The song is easy going, yet gentle song where the latin rhythms is used tastefully without clashing with the idea of a lullaby. The arrangement is superb and the young singer gives a confident and at the same time very relaxed performance on a stage.
This song continued Germany's good streak in the early years of Eurovision with 4th position in the final results and Wyn Hoop would continue to have a good career in the German showbusiness until the end of the 1970's. After retiring, he has written articles and books about sailing and travelling.
My points 4/5.
