Yeah, that's the thing about their early boy band songs. Amazing harmonics, great sound—questionable lyrics. It's mostly typical horny boy band stuff, no different from early Beatles boy band stuff, but more direct in what they were talking about. Everything they did post-Pet Sounds was much more interesting, well, at least until the late 70s when Mike Love took over the band and decided they needed to be an oldies band, going back to their boy band stuff and playing it exclusive and forever. Not that that middle period stuff didn't also have questionable lyrics, but at least it was more interesting.

BTW, that dub remix you posted is great!
