Marius Muller Westernhagen (6 December 1948 in Dusseldorf, North Rhine Westphalia) is a German actor and musician. 　　Possibly best known for the maudlin hit "Johnny Walker", Marius Muller Westernhagen has been a feature in German rock music since the mid-1970s. Marius is known for his energetic public concerts, and his fans know his anthem-like songs by heart. 　　While keeping away from the merely fashionable, Marius has nevertheless managed to reinvent himself every few years, and is popular with multiple generations of Germans. As a result of his singing which almost exclusively in German language in a country where pop and rock are primarily performed in English, Westernhagen originally seemed destined for obscurity, but has managed to use this to his advantage, defining himself as a durable alternative to the perceivably manufactured English-language hits of America and the UK.
