When Dolly Parton, Emmylou Harris
and Linda Ronstadt recorded it in 1999 for their collaboration Trio, they got some unique insight into the song from the man who wrote it. Said Parton: "When we were doing the Trio album, I asked Linda and Emmy what it meant, and they didn't know. So we called Neil Young, and he didn't know. We asked him, flat out, what it meant, and he said, 'Hell, I don't know. I just wrote it. It just depends on what I was taking at the time. I guess every verse has something different I'd taken.'"
