Since I keep dreaming about it...

The first time I made the mistake to listen to I Like Chopin and the melody was gone. This time, although I remembered none of the lyrics and melody search engines couldn't help me, going through the German charts from 1981 onward did the trick. I knew there had to be some connection to Gazebo, so I did identify the composer, only that he kinda hid himself.
