I don't think that's at all the real message with "Imagine," or, I should say (as it wAS the 1970s, so yeah, there is a bit of that in there, but that was the time) MOST of what the song is is a vision for how mankind SHOULD be and CAN behave and CAN be and become, rather than what man IS.
To put what I mean in perspective, Let It Be is asking (or, rather, telling) us to "all get along, ie, LET IT BE" whereas Imagine is asking you to do just that--IMAGINE if things were this way, how great would it be if we had a different outlook, and that's really the focus of the song, this isn't just "stop the war," but rather asking people to Imagine what life would be like if human priorities would be different; if more people placed a greater emphasis in their lives on the non-material and the idealized concepts rather than simply accumulating wealth and security through any means necessary like any other animal does with food and sex as the currency...if people acted more on their own accord and less in a us vs. them situation, saying ME before WE and placing the self before the state...Imagine such a world--and do you like it, or is it even worth trying?
I don't see it as preaching, then, so much as almost a proposal of a new plan for life...in song.
Really? Yellow Submarine? That song is CLASSIC how can you hate that, it's jsut a fun song, it's not really even bAD...just because it's not a smash hit song, it's just a fun, quirky piece, it's not trying to be anything else...and yet it IS more than the sum of its parts, because that little quirky piece became the theme for one of the best quirky movies (and I'd vote one of the Top 20 Best Animated Films EASILY, this trumps a LOT of the factory-produced Disney/Dreamworks crap, especially of modern day) in the film "Yellow Submarine."
Tazman...eh, it's OK, not great, not bad, I don't see how that can be bad...
To me, the WORST Beatles song has to be one where you ask, like you'd ask of any master who fouls up, "HOW could HE/SHE/THEY have made THAT?" It's so bad that you almost want to find an excuse and say that some how they didn't do it...
Take Shakespeare (as obiwanobiwan always needs to mention him and Nietzsche in any thread, those two names out of the way and we're there lol.)
Hamlet, Othello, Macbeth, King Lear, Richard III, A Midsummer Night's Dream, Romeo and Juliet, Twelfth Night, The Merchant of Venice...
And that's just off the top of my head, and that's the POINT, you can name SO MANY great ones SO EASILY with the best, when you come to that hitch in the road, it's so incredible, because it's so incredibly below what you'd expect you wouldn't believe it.
There are folks who, even barely after Shakespeare's day, REALLY wanted to say "Titus Andronicus" wasn't really written by the Bard, it couldn't be, it was so bad (and I use that term for them because I actually love the work, it was his first tragedy and it does really show, it's very rough and very raw, not at all as good as that string of later ones I mentioned, it's over-the-top gruesome...14 deaths in all gives it the highest body count, 9 of these deaths occuring on stage, and to top it off we have tongues and hands and limbs being hacked off, people being sacrificed to gods, and a rape...if you want to see a really raw, REALLY Gothic Shakespeare piece, I'd say this is more Gothic at least in mood and gore than even Macbeth, famous for being so dark) they had to disown it.
By that same topic, what clashes so badly with the Beatles' usual level of excellence?
Not Yellow Submarine, that fits right in with their quirky pieces that they made, they made quite a few that were quirky like that song, especially in the period that came out, so even if you dislike the song (and I really don't see why, again, I think it's superb for the fun, unassuming little ditty it is, and it's nice to here Ringo get to sing a song people actually like and listen to for a change) it can't be the worst, you can't ask, all to appropriately for the Beatles, "What the hell were they smoking when they made THAT?" ;)
Same with Taxman--it might not be the best, but it fits their style, it just lacks some parts to make it one of the best or ones that we love so much.
So for my pick, I propose two, and one especially...
Revolution 9 (can't believe no one said that one) and Wild Honey Pie.
And of those two...I'm going with Wild Honey Pie, BOTH are just insanely ridiculous to hear, but at LEAST with Revolution 9 I it has three things going for it--it's so bad and ridiculous you can laugh and spoof it, it has super-easy lyrics (Numbah nine...numbah nine...numbah nine...numbah nine...) and you can sort of write it off as basically "The Beatles Got High And Decided To Screw Around With The Sound Editing To Make A Ridiculous Tape." I can picture them high...we all can...especially John...so yeah, I can at least SEE how they could've made that.
But Wild Honey Pie? :O MY GOD! I might be short, and yet I can't get through it, I sat through it a couple times just to do it but even at maybe a minute and a half, I can't get through it, it hurts my ears...the singing's horrible, there's nothing IN the song, the tune is awful, that twanging noise drives me up the wall...
AHHHHHHH!!!!!!!!
Worst one...
