Graham Nash [left] isn’t the owner of the biggest whiskers in this picture, but he did make up the refreshing Brit-pop quadrant of Crosby, Stills, Nash & Young. This photo by Henry Diltz is from one of my favorite photo sessions of all times, from the tour on which ‘4 Way Street’ was recorded. The center fold of that album cover hung on the wall in my room for a long time, a single shot taken within minutes of this one, as I remember it. I found this one decades later, but now as then, the harmonies these guys made seem like they could only have come from angels. Yet they were so solid they made you feel like you could reach out and catch the notes in your hand.
