Matt Jardine on lead vocals, with Al Jardine, Carnie Wilson, and Wendy Wilson on backing vocals, Ed Carter on bass, Debbie Shair on keyboard, Bobby Figueroa on drums, and Probyn Gregory (multi-instrumentalist). In the intro to the song, I think Al is referring to the first car song he worked on upon returning to The Beach Boys in late 1963? Although he technically returned in time to perform on the Surfer Girl and Little Deuce Coupe albums, so I dunno if that's right...?
