Neil Young - heart of gold, 1972

"The song, which features backup vocals by James Taylor and Linda Ronstadt, is one of a series of soft acoustic pieces which were written partly as a result of a back injury. Unable to stand for long periods of time, Young could not play his electric guitar and so returned to his acoustic guitar, which he could play sitting down. He also played his harmonica during the three instrumental portions, including the introduction to the song."
