Otto Von Wernherr is a German singer. He was born in Heidelberg under the name Ottheinrich Werner. Today, he's best known for working on some of his songs with singer-songwriter Madonna, before her solo career. In 1981, due to financial difficulties, Madonna did backing vocals on three songs of the singer: "Cosmic Climb", "We Are the Gods" and "Wild Dancing". After Madonna became known, Otto reworked the three songs, leaving the backing vocals more evident and re-released them with Madonna's photo on the cover.
