Listening to this KHJ aircheck, counting down the big hits of their Boss Radio time, the Boss 93 of 1965, the host mentions how KHJ had a "world premier" of The Beach Boys' California Girls.
Boss 93 KHJ
Great the great station was the first to play the great group's great song, one of their most known hits.
FYI... the song that played before The Beach Boys was Sonny and Cher's Just You, according to the music references below the Youtube video. I didn't recognize it and see it charted nationally @ No. 20, but isn't listed in that link as charting on KHJ.
Okay, so what you need to know for any of that to make sense is:
1: KHJ's 9:00 a.m.-12:00 noon disc jockey from the launch of Boss Radio in late April until September was Roger Christian, Brian Wilson's songwriting partner (though he did not help write "California Girls"). That gave the still-young and not-yet-highly rated KHJ an edge in getting the exclusive on "California Girls".
2: "Just You" was the flip side of "I Got You Babe". The reason you don't see a KHJ chart number for it was that KHJ did not have its own chart for its first 73 days.
Boss 30 issue #1 came out on July 9, 1965.

From the day it launched until that moment, KHJ simply played what KFWB was playing---and on KFWB, "Just You" made it all the way to #10:
And the reason "Just You" and "California Girls" ended up next to each other on the KHJ Big 93 year-end survey---was that "California Girls" only peaked at #8 at KHJ.
