This one by Yvonne Carré was a Decca release in Germany. Carré was a German singer, but had a hit in Japan with "Sukiyaki" and toured the country many times. She started her career in the 1960s in Germany. I think her career isn't much of interest here, you can also go to her website. She is married to Frank Valdor, an orchestra leader. I like Carré's Decca single very much, that's why I posted it here. Just looked for something "strange".
