Moondog - Whats my line?

From the late 1940s until 1974, Moondog lived as a street musician and poet in New York City, busking mostly on the corner of 53rd Street and 6th Avenue in Manhattan. He was not homeless however, or at least not often—he maintained an apartment in upper Manhattan for most of his life.[3] In addition to his music and poetry, he was also known for the distinctive fanciful "Viking" garb that he wore, which included a horned helmet. He partially supported himself by selling copies of his poetry and his musical philosophy. Because of his street post's proximity to the famed 52nd Street nightclub strip, he was well-known to many jazz musicians and fans. (From Wikipedia)
