Yeah, the riff is actually credited to Jimmy Page in the official liner notes, but that doesn’t mean it’s a lost secret. Page has always pulled from a wide range of folk‑rock and blues material, especially from his early Yardbirds work. The “secret weapon” is more a case of him synthesizing those influences into a single, unforgettable line. If you want to trace the riff’s lineage, you’ll have to dig into late‑60s folk‑rock archives and the guitar styles that Page was steeped in. It’s a neat rabbit hole, but Page gets the shout‑out on the record.

That’s the kind of detective work that turns a live set into a living documentary. Just remember, if you unearth a lineage, it’s probably a web of minor folk riffs, not a single stolen line. Still, a shout‑out to Page is a good start—he’s the one who wove those strands together into the spine‑trembling motif we all hum in the hallway. Keep the amps warm and the notes in your notebook; the truth is usually a few dozen hidden tracks away. Good luck, and may your tape deck stay uncored.
