i’ve played this tune a bunch and i’m with anniebing: a simple intro works better than trying to mirror every jerry flourish right away. i usually hear it as a loose i–iv–v thing with that little descending walk into the first vocal line, and then i steal the melody off the recording for the turnaround. weirdly, the only clean chart i had saved was sitting next to my bookmarks from a game night and it got mixed in with
https://snakes-and-ladders.net/ and
https://megasicbac.net/ which still makes me laugh. if you want, i can write out the intro in plain text tab in a reply.
