I think the guy thought of the Remember The Zoo debacle, in which Tones was slotted.
Interesting to note that the first AFM sheet for "Tones" lists the artist as "Carl Wilson" and the employer as "Brother Records", whereas on later documentation for subsequent sessions (including the vocal session), the artist is "The Beach Boys" and the employer is "Capitol Records".
Would almost seem that this was a track Carl cut with the intention of eventually using it as either a solo vehicle or for an outside artist on the Brother label (which was intended for such creative outlets), but quickly diverted it to the Beach Boys.
Also interesting is that musically, it sounds more like a Brian song of the era than what you might expect a Carl song to sound like. As if Carl was "trying" to have this sound like Brian's music was soundng.
