WIKIPEDIA:

“ Udo Jürgens (born Udo Jürgen Bockelmann, 30 September 1934, Klagenfurt, Carinthia, Austria) is an Austrian composer and singer of popular music whose career spans over fifty years. He has written more than 800 songs and sold over 100 million records.
He is credited with broadening German-language pop music beyond the traditional postwar schlager in the 1960s by infusing it with a modern pop appeal; his exceptionally tuneful compositions and sophisticated arrangements attract fans of all ages, and even in his 70s he continues to fill the largest concert venues in Germany, Austria, and Switzerland.

Career
In 1950, he won a composer contest organized by Austria's public broadcasting channel ORF with the song "Je t'aime". He wrote the 1961 worldwide hit "Reach for the Stars", sung by Shirley Bassey.
In 1964, he represented Austria for the first time at the Eurovision Song Contest with the song "Warum nur warum?", finishing sixth. The UK participant, Matt Monro, was impressed with the melody and covered the song (with English lyrics by his manager Don Black) as "Walk Away", which reached number four in the UK Singles Chart and number 23 in the US Billboard Hot 100 chart.
