That single was released in the Western part of Germany, and although it didn't become a hit, it is a decent version of that song. It is every bit as (over)emotional as the original track. The big success arrived a year later, when the next single 'Verdammt' was released. By the time Wolfgang's second solo album was released, Germany was no longer separated between East and West.
