Ever heard of the term "timeless?" Some songs are timeless, and I never tire of singing them. And apparently people don't get tired of listening to them because they ask for songs I've been doing for 30 years (as I do when I hear other performers. Most new songs (including mine) will turn out to be "disposable." They too have their value. It's good to have a mix of the two. If you are a performer and not just a musician the audience will let you know what they want to hear. They'll probably want to hear some of the old songs, and welcome new ones, too.
