Os Beatles eram, afinal, de direita

Há vários sites dedicados à interpretação de letras de músicas. Percorri alguns à procura de pistas sobre isto. Vietname, não Vietname, comunismo, não comunismo, fiquei na mesma. Ninguém me explicou. Mantenho a opinião de há muito, ou seja, de há 15 minutos atrás, quando decidi prestar atenção ao iPod: esta é uma letra que podia ter saído do Largo do Caldas.

You say you want a revolution
Well you know
We all want to change the world
You tell me that it's evolution
Well you know
We all want to change the world
But when you talk about destruction
Don't you know you can count me out

Don't you know it's gonna be alright
Alright, alright

You say you got a real solution
Well you know
We don't love to see the plan
You ask me for a contribution
Well you know
We're doing what we can
But if you want money for people with minds that hate
All I can tell you is brother you have to wait

Don't you know it's gonna be alright
Alright, alright, al...

You say you'll change the constitution
Well you know
We all want to change your head
You tell me it's the institution
Well you know
You better free your mind instead
But if you go carrying pictures of Chairman Mao
You ain't going to make it with anyone anyhow

Don't you know know it's gonna be alright
Alright, alright

Alright, alright
Alright, alright
Alright, alright
Alright, alright
