Can anyone tell me the name of the 70s horror...

Hey can anyone tell me the film.

All i remember is a girl looking out of a window and seeing something that sings "Boys and girls come out to play..."

If anyone can greatly appriciated.

I did a search for you, because I was bored, and one thing I found was a TV show with an episode called "Boys and Girls come out to play" The TV show was The Troubleshooters-- I have no idea what it is.

BUT There is also a nursery rhyme by that name with that line and could be used in anything, i couldn't find anything that seemed like it might be horror...
