One of the old clichés of Hollywood movies is the singing mountie. Rose Marie with Nelson Eddy http://www.imdb.com/title/tt0028207/ is the best-known example.
I had an idea for movie about a very different kind of singing mountie. A true story I read about back in high school in Winnipeg about 1970 or 1971 inspired my idea.
Members of a local bar band was arrested in a drug investigation. It turned out that the lead singer of the band was, in fact, an undercover mountie. The band was just about to break out big when the arrests came. One detail I remember was the drummer said that he would still like play in the band with the mountie.
I thought that a standard rock band rise to success story could use this as a twist ending. Maybe someday I will follow up on this idea.
