An unreleased, early demo version of the Beatles’ classic “What Goes On” could be yours if the price is right. An acetate demo of the song from early 1963 features John Lennon singing and accompanying himself on acoustic guitar with Paul McCartney singing harmony on the chorus. The song itself actually predates The Beatles. Lennon wrote it when he was in the Quarrymen. The acetate is being auctioned on eBay and bidding ends October 1. As of Thursday night, bidding stood at 2,222 pounds or around $3,016.
