The Coda Experiment: How 'Can't You Hear Me Knocking' Got Its Legendary Jam

The story goes that after the band finished the main take of “Can’t You Hear Me Knocking” during the Sticky Fingers sessions, nobody bothered to stop the tape. The studio just kept rolling as the band vamped on a loose, latin-tinged groove. That leftover jam—Mick Taylor’s liquid guitar, Bobby Keys’ honking sax, Charlie Watts’ shuffling hi-hat—ended up being too good to cut. So they slapped it onto the end of the track, and suddenly a three-minute rocker became a seven-minute epic.

What’s wild is how accidental it felt. The main song was already a tight Keith Richards riff-rocker with a drug-dealer lyric, but the coda turns into a completely different animal—sleazy, exploratory, almost jazzy. Bobby Keys later recalled that he just started blowing over the groove, and the band locked in. The tape op apparently didn’t even know they were still recording. That spontaneous decision gave the Rolling Stones one of their most beloved deep cuts, and it’s a perfect example of how studio serendipity can define a band’s sound.
