Across The Universe is a John Lennon tune that originally appeared on a benefit album for the World Wildlife Fund (the real WWF!) and later appeared on Let It Be. The most authentic version can be found on the reissue Let It BeРІР‚В¦ Naked. The song opens with a short melody, harmonized in 6ths, played on the 1st and 3rd strings, before settling into a little strumming over F#m and A. The verse has an interesting variation in a couple of spots where John puts an extra beat of A in a measure to let the words flow a little smoother.
