Buckingham and Nicks dismissed the rest of the band for a sublime "Landslide," which she still does better than anyone. During his solo, she stepped behind him and placed her gloved hands on his shoulders, lightly tapping her fingers to the beat. The depth of their shared feelings blazed forth fully on Buckingham's wonderfully delicate "Say Goodbye" from the new album, a song about severed ties sung directly to each other. "Once you said goodbye to me," he whispered to her, "now I say goodbye to you." It was a heartbreaking moment that some in the too-noisy crowd missed.
