Lyric discussion by Black&GreenAchilles 

Cover art for Vegetable Man lyrics by Pink Floyd

One of the best songs Floyd ever did. Absolute f*cking genius. If he hadn't already started to invent punk with Astronomy Domini this would have been the invention of punk.

It's like the lyric in Flaming that goes - you can't see me - but with much less yippee about it. So I agree it's autobigraphical, but it says much much more about how limited the rest of the band were and even more about how crap the Floyd audience, and 99.9% of people, are.
