What movie is this song from?

I know the lyrics to this song but I don’t know what movie it is from…

He wants to kill a man.
Maybe one, maybe two or maybe three,
maybe four, maybe five or maybe seven
maybe seven, maybe nine
he wants to kill a man

maybe…he want to kill a man
maybe…he wants to kill a man he wants to kill a man.

That’s all I know from the song off hand. Please help! This is driving me crazy!!

One After Another (Uno Dopo L’altro) with Richard Harrison (1968).
Here is a link for a soundtrack:
