And come on. Love you?

Don't even get me started. Again, I think some fans are WAY too forgiving with the
childlike childish lyrics because of Brian's state at the time. But like it or not, it wasn't private therapeutic writing assignments. It was a major label release by a MAJOR recording act. I got it early in my foray into Beach Boys fandom (Endless Summer > Spirit Of America > In Concert > Good Vibration/Great Concert! > Love You) and it put me off the band for YEARS and it wasn't because of the voices!
In hindsight I wouldn't be surprised if the band KNEW it was crap and allowed Brian the therapeutic indulgence since they knew they were done with Reprise. (I know it's bad business sense to release something you know is bad but this band ain't exactly known for always making the best decisions.

)
Mike and Al (despite their apparent change of heart since) did indeed give Brian grief for it at the time.
