I got to know Mary Roos in 1984, when she represented Germany in the Eurovision Song Contest with song Aufrecht Geh'n. I was impressed with her voice which was vulnerable and strong at the same time. It was many years later that I heard and saw hers first Eurovision entry, which took part 12 years earlier.
When watching for the first time a bad quality VHS copy of the 1972 contest held in Edinburgh Scotland I was puzzled by her performance. Here was 23 years old singer singing un upbeat happy song with the same vulnerable strong voice I had heard singing a heartbraking ballad of separation in 1984. Somehow I felt her voice did not mach the song Nur die Liebe lässt uns leben.
During the years I've grown to appreciate her performance in 1972 as much as her appearence 12 years later. The song is good and she is clearly having good time on stage. The relaxed feeling, smile, the sparkle in her eyes (contrary to her 1984 performance) and of course her confident singing make the song work and the third position in the final results was well deserved.
My points 4/5.
