I was actually surprised to find that so many people are better acquainted with the Perrault version of Little Red Riding Hood, compared to the Grimm version. Stephen Sondheim’s Into the Woods is actually the most vivid example of fairy tales told in a modern way, and the musical is very faithful to the Grimm brothers’ versions; having seen the 1991 version of the musical at an early age, it tends to be the first thing I pull from when considering fairy tales.
That being said, the sexual nature of the Little Red Riding Hood story is really rather explicit in Into the Woods. The wolf always looks more like a man than an animal, and Little Red Riding Hood is typically played by an actress in her mid-to-late teens. When the wolf first encounters Little Red Riding Hood in the woods, he sings “Hello Little Girl” to her, featuring lyrics like “Look at that flesh/Pink and plump/Hello, little girl/Tender and fresh/Not one lump/Hello, little girl.” The song is essentially a back and forth between the two, the wolf trying to convince her to stray from the path while the girl attempts to avoid temptation.
Afterwards, when the girl and her grandmother are saved by the Baker (in lieu of a Hunter), Little Red Riding Hood sings “I Know Things Now,” some of the lines of which are, “And he showed me things/Many beautiful things/That I hadn’t thought to explore” and “And he made me feel excited/Well, excited and scared.” What’s interesting is that Little Red Riding Hood is decidedly childlike for the rest of the musical; it’s only in her encounters with the wolf that she appears otherwise.
If you’ve never seen any of Into the Woods, I highly recommend watching at least the Little Red Riding Hood numbers. It really brings the Grimm version to life and definitely “washes the windows” as Tolkien would say.
