If there’s one tune that’s sure to get stuck in your head and rattle around all day, it’s the classic Mahna Mahna. This early appearance during a 1969 episode of Sesame Street will crawl into your ear and won’t let go. “Mah Nà Mah Nà” was originally written by Piero Umiliani and first appeared in the Italian film “Sweden: Heaven and Hell” (Svezia, Inferno E Paradiso).
