Old movie title of a horror movie,with a crazy lady that sat in a chair and sang hey nonny nonny nonny. Men are so inconsistent. And she would stab these scissors through her kniting, when she sang this song? Please help us.

Okay, while I cannot prove it with YouTube clips or imdb.com plot summaries, the savants at another site are confident that the answer is Two for the Money, a 1972 TV movie with Richard Dreyfus and Mercedes McCambridge (she was the insane killer).
