In 1968, back from their disastrous confab with the Maharishi, the Beatles took their acoustic guitars to George's house in Esher and set down what has since come to be known as the Esher Demos. Most of the songs were later rerecorded for the White Album, but it's fascinating to hear how well-formed so many already were. Here, at its most stripped down, "Rocky Raccoon" even has the saloon piano solo (though mouthed rather than played). Some scrapped songs eventually turned up on solo albums, including John's "Child of Nature," which many will recognize as "Jealous Guy."
