Whatever you are most comfortable with. My dad, who is 84, plays banjo, fiddle, mando, and keyboard, and sings. He uses back up tapes, of himself, all of the time. It sounds okay and he never gets accused of karaoke, but there are many times when I wish he would just play solo instrument and sing. It makes him feel better, though, as it is more like the dance bands he played in. He saved his solo stuff for round the campfire with us kids.:-)
