"I'm Going Slightly Mad" is a Queen song, written by Freddie Mercury. It is the second track on the 1991 album Innuendo. Although the accompanying music video appears to project the song as being very humorous and light-hearted, many people believe that the eerie keyboards and bleak lyrics reflect darker undertones, inspired by AIDS-induced dementia. Actress Cleo Rocos has confirmed this notion, stating that Mercury had explained to her and mutual friend Kenny Everett that the song documents the tragic mental decline he suffered during the final years of his life.
