Shock rocker Marilyn Manson demands an oxygen tank backstage at his shows. The Disposable Teens hitmaker's backstage demands have been exposed in his tour rider, which reveals he wants an oxygen tank and a mask to be provided behind-the-scenes for his personal use. The document, obtained by Thesmokinggun.com, states, "Promoter shall provide one oxygen tank with regulator and mask for the artist's sole use. It is imperative that this can be self-administered." Manson also asks for black drapes in his dressing room, while his list of preferred foods shows his softer side - the rocker likes to have a supply of Haribo gummy bears, as well as chips, chocolate and ginger ale.
