Neil Young: No One Seems to Know

Despite all the hiss on the recording, I've always been partial to this short, haunting piano ballad. It debuted in 1976 (this version comes from a concert in March of that year in Osaka, Japan). After laying dormant for years, it was revived for his 2007 tour. But like dozens of his songs, it remains officially unreleased.
