King and Tolkien

It’s clear, especially in his fantasy, that King is influenced by Tolkien - as most authors are in that genre. But in the last two books I’ve read, he’s directly referenced the Lord of the Rings: Devin Jones reads it in his room throughout the book; and now in The Talisman the narrator references it a number of times, mostly when discussing the Ents after Jack enters the forest.

I’m curious if anyone can think of any other time Tolkien and his work pops up in King’s books?
