I had never heard this before:

Wikipedia says it's Red Rhodes. Pretty cool!

Red also played on Hold On Dear Brother from the Carl & the Passions album a couple years later: https://youtu.be/B3Xbg7v3Fwg

and an unreleased Beach Boys song called We're Together Again, with James Burton on dobro: https://youtu.be/TICRidVYSns

and Al Vescovo played C6 on the songs Diamond Head and Little Pad, DH is a full-blown steel guitar instrumental: https://youtu.be/h8l47emr2U4

they did a few other things with steel also.
Buddy Emmons claimed to have done a Beach Boys session but couldn't remember the song. and he's not listed on any of their albums but it could be this one: https://youtu.be/22z03ZQtpe8

May I add another one, this time with Mama Cass?
