via this post, the genesis of Yello's "Oh Yeah" (1985):
First I did the music and then I invited Dieter to sing along, and he came up with some lines which I thought, 'no Dieter, it's too complicated, we don't need that many lyrics'. I had the idea of just this guy, a fat little monster sits there very relaxed and says, "Oh yeah, oh yeah". So I told him, 'Why don't you try just to sing on and on 'oh yeah'?... Dieter was very angry when I told him this and he said, 'are you crazy, all the time "Oh yeah"? Are you crazy?! I can't do this, no no, come on, come on.' And then he said, 'some lyrics, like "the moon... beautiful", is this too much?!' and I said, 'no, it's OK', and then he did this 'oh yeah' and at the end he thought, 'yeah it's nice', he loved it himself also. And also I wanted to install lots of human noises, all kind of phonetic rhythms with my mouth; you hear lots of noises in the background which are done with my mouth.
