Interestingly, Brian Wilson gave ‘Surf City’ to Jan Berry who made minor changes along with changing the title. If you listen to the song it’s pretty much a straight Beach Boys tune. Pretty nice gift as it reached #1 on the record charts.
Yes. That's a nice little piece of Surf Music history.
There are stories of collaboration on other Jan and Dean songs between Jan Berry and Brian Wilson.
I've also read tales of members of both groups sitting in on recording sessions with each other.
