Cover art for Wooden Ships lyrics by Jefferson Airplane

Airplane version is undoubtedly best, but the CSN version is still pretty damn good.

The lyrics at the top definitely don't fit the version of the song I'm familiar with. I always got a 'nam vibe from it, along with the feeling that whoever wrote it just wishes to retreat to a simpler civilization, away from all the BS infesting America. 'Silver people' is used to directly contrast 'wooden ships', probably to represent the infrigement on humanity, nature, and simplicity by industry and cities, or even more likely, by war.

Maybe it's just to symbolise their opposal to war?
