After her tumultuous relationship with Gordon Lightfoot ended, Cathy Smith headed to California to pursue her own musical dreams. She was briefly a backup singer for Hoyt Axton. She also had a brief interlude in Paris, where she met The Rolling Stones, who she would later provide drugs to. But it was her association with John Belushi that made her notorious. In March of 1982, she injected Belushi with a mixture of heroin and cocaine that proved fatal. The media and legal drama that followed was just another part of her pattern of being taken advantage of by others.
