I am looking for the title of a movie. It was made in the seventies. It was about a couple who were fleeing the United States' Government. They had already had a baby. The woman was pregnant again. In this futuristic society people could only have one baby. They were fleeing to Canada. Does anyone...

I heard a song on a radio at work the other day and I was just wondering if any one knows what group did it, the words I remember are "you ain't got no lover. I could have the words wrong but I'm pretty sure they're right.
