Imagine is a great example of people not listening to the lyrics of songs. I am one of the few who do, and so of course to me it was clear that is is nothing but a song in praise of Communism for a long time.
Better they should sing "Tax man" or even "Rocky Racoon".
I recall Buckley mentioning the song several years back and relaying a few of the lyrics but could not go on because it was a family column and he didn't want the kiddies to read it. I'll see if I can find a direct quote.
