From the "Rubber Soul" album. A real "joint" Lennon/McCartney song writing effort, both in terms of them writing together, but also they were both smoking a lot of pot at this time!!! In song writing terms, it really starts their move towards them both buying into the idea of "Love" being a philosophy and a way of live. They have an almost evangelical zeal for it, "I'm here to show everybody the light"!!! Talking about this song John is quoted as saying, "You read the words, it's all about - gettin' smart. It's the marijuana period. It's love, it's the love-and-peace thing. The word is 'love', right?" George Martin plays harmonium.
