Wolfman JackWolfman Jack (January 21, 1938-July 1, 1995) was the stage name of a popular disc jockey in the 1960s and 1970s. Born Robert Smith, he came to prominence in the United States in the 1960s as a disc jockey on Mexican radio stations, including a stint with XERF-AM, which broadcast into the United States with a powerful transmission of 250,000 watts, five times as powerful as American stations were allowed to use.
In accordance with his stage name, he frequently punctuated his broadcasts with howls, which, along with his gravelly voice, made him instantly recognizable. This style was modelled, at least in part, on bluesman Howlin' Wolf.
He became internationally known in 1973 by appearing in the George Lucas film American Graffiti. His broadcasts tie the film together and catching a glimpse of the mysterious Wolfman is a part of the plot.
Afterwards, he appeared in several films and television shows (including Midnight Special and his own show, The Wolfman Jack Show). He also furnished his voice in the 1974 Guess Who's tribute, the top 40 hit single, "Clap for the Wolfman".
