That's from "CEMETERY GIRLS" by BARNES & BARNES!

I'll let entrant Amanda "ac27" Cohen explain further:
"It's Bill Mumy (known at the time as Billy Mumy) as Anthony Freemont in the Twilight Zone episode 'It's a Good Life.' And of course, Barnes and Barnes (aka Robert Haimer and Bill Mumy) used bites from that episode in their macabre melody, 'Cemetery Girls.'"

You kids are out of the cornfield!
