After that stint at the Top 40 AM outlet, he would take the offer of being the host of a radio show on CKMF-FM at the start of the fashion for disco.
Montpetit was also hired to host a disco dance show on Montréal's private French-language TV station, Télé-Métropole.
However, he took advantage of the opportunity and was known as Montreal's "King of Disco", accepting sizable payment in cash or drugs from various club owners for spending time at their establishments.
Douglas Coco Leopold, who also worked for CKMF and was a prominent disco radio and TV personality, accused Montpetit of the murder on the air.
[1] A fictionalised version of Montpetit, played by Patrick Huard, is one of the central characters in the 2010 Canadian film Funkytown.
