"Verheiraten" on the Cabaret movie soundtrack.German makes a great language for novelty songs. I have several in mp3 form on the hard drive at home, including a few by Frank Zander (including the perfect "Oh Susie") and some by Udo Lindenberg.
It's hard to imagine wooing a woman by singing in German though, I'll grant. Perhaps that's why yodeling is essentially wordless? Or was yodeling not used to woo?
