[observation, 2015] Every year that goes by the songs become more special, and the lives of the people in the audience change. Life changes. So when I come back every year and sing those songs, it's like a time machine for people. And I don't shy away from the hit records. I'm not shoving a lot of new stuff down people's throats--not at this stage in my life. I know why they're coming to see us. We try to send everybody home happy. So they are going to hear the songs they came to hear.
