Funk Babblings

Last night I was listening to the great Richard & Linda Thompson album Shoot Out The Lights. As the song "Back Street Slide" was drawing to a close, I realized that part of the guitar part in the closing sounded a lot like Led Zeppelin, who I haven't really listened to much since my early years of college. Going by memory, I think it's the song "Kashmir" (from Physical Graffiti) that I'm thinking of.

Though both are British, these are not artists that I would normally associate together. Anyone know both of them, and can tell me whether I'm crazy?
