Today in Intellectual Property news: copyright law invades the domain of Bavarian beer-hall yodeling.

The money-spinning power of “horlla-rü-di-ri, di-ri, di-ri”, the famous chorus of the Kufsteinlied, which is capable of making even the hardiest of lederhosen-clad Germans go weak at the knees, has been keenly felt this week in a Munich courtroom battle over who owns the copyright.

The heirs of Karl Ganzer, the Austrian composer of the 63-year-old beer-hall hit which is said to be Europe’s most-played folk song, were yesterday successful in their attempts to sue the music publisher Egon Frauenberger, who claimed he had written the song’s refrain and therefore had a right to a twelfth of the royalties.

The most famous version of the “Kufsteinlied” was recorded in 1968 by Franzl Lang, the Jodlerkönig. Here he is singing it in 1991. Now I’m thirsty.
