Cathy Smith was an occasional backup singer and inspired Gordon Lightfoot's hit song "Sundown."
The woman who played a key role in the death of comedian John Belushi passed away at the age of 73.
Cathy Smith admitted to injecting the "Saturday Night Live" vet with a lethal combination of heroin and cocaine -- dubbed a "speedball" -- on March 5, 1982 at the Chateau Marmont in West Hollywood. Belushi suffered an overdose as a result at the age of 33.
Smith died on August 18 in Maple Ridge, British Colombia after her health had been in decline over recent years, according to The Globe and Mail.
