"Revolution" was The Beatles statement on what they were seeing at the time. Written by Lennon and credited to Lennon - McCartney.
I wanted to put out what I felt about revolution. I thought it was time we fucking spoke about it, the same as I thought it was about time we stopped not answering about the Vietnamese war when we were on tour with Brian Epstein and had to tell him, 'We're going to talk about the war this time, and we're not going to just waffle.' I wanted to say what I thought about revolution.
I had been thinking about it up in the hills in India. I still had this 'God will save us' feeling about it, that it's going to be all right. That's why I did it: I wanted to talk, I wanted to say my piece about revolution. I wanted to tell you, or whoever listens, to communicate, to say 'What do you say? This is what I say.'
