I remember it well Pubbie! I tore up that chugga-chappa lick on the bridge. That song was first recorded by The Showmen in New Orleans in 1962 by Joe Banashak, produced by Allen Toussaint. The original "kick sheet" (drum music shorthand) handwritten by Toussant was in their book. They re-recorded it with Barrett in '65 because recording techniques had improved from two track to four allowing them to go from a live session to "bouncing" the tracks and over-dubbing vocals in isolation booths (the "Philly Sound").
I had no idea who Toussaint was until I got to New Orleans in '74 and he produced a recording at Jazz City Studios for The Navy Steel Band. Dropping Norman and Danny's names got me invited to dinner at
Brennans with Mr. Toussant and his entourage (including Art and Aaron Neville, Branford Marsalis and Danny Barker, founder of the Dirty Dozen) after the session (much to my NCO's dismay)! Toussant remembered writing the charts for the showman and telling them to start a book of their own and hire pick-up drummers and axillary horns on road-trips to read the charts. In those days that was SOP and you couldn't get in a publisher's office to play your songs without a written "lead sheet". I learned a lot about the music business from those guys.
