The song "Wish You Were here" was obviously written for Syd, as the album is a tribute to him, and many people have very differing interpretations of it. But there are a few lines which I think connect to some of Syd Barrett's own lyrics.
"Cause we're the fishes and all we do, the move about it all we do" from "Terrapin"
"We're just two lost souls swimming in a fish bowl, year after year" from "Wish You Were Here"
(pretty much two different ways of saying the same thing)
"Please hold onto the steel rail" and "Skeleton kissed to the steel rail" from "If It's In You"
"Can you tell a green field from a cold steel rail" from "WYWH"
(I just thought it was kind of odd that out of all the things he could compare a green field to, he picked a steel rail)
"Send a cage through the post, make your name like a ghost" from "Baby Lemonade"
"Did they get you to trade your heroes for ghosts?" and "Did you exchange a walk on part in the war for a lead role in a cage?" from "WYWH"
(Syd's line, I'm speculating, has to do with the money he would get from Pink Floyd royalties in the mail, which kept him from needing to do anything else to earn money, such as playing music again. That kept him in sort of a cage, the cage of his perpetual routine. The ghost bit I'm thinking had to do with his need for the members of the Floyd to just leave him alone, or to forget the painful memories, making them become like ghosts. The "they" Roger refers to could be the drugs Syd had taken so much of, and he blames them for turning Syd's once admirable feelings towards the Floyd to no more than empty, fading memories. In the next line I imagine him to be questioning Syd with "did you give up a background role in the Floyd (or making music in general) for a lead role in your own isolation?")
The last utterance of "wish you were here...." in the song seems kinda funny to me, because Roger got what he wanted, but probably not in the way he was meaning it. Syd actually WAS there at one point during recording, but he still wasn't able to connect in the way that I think the whole band missed...
So what do you guys think? Is there a connection?
