You will never go wrong with gospel hymns and in most cases they are preferred. Amazing Grace has always been the most requested for me, Will The Circle Be Unbroken, I'll Fly Away, In My Fathers House are some other crowd favorites. Songs about mom and dad and the old home place are always popular Green Green Grass of Home as an example. There will be folks of differing age groups, it is not always just elderly in nursing homes. Generally deduct 50 years and look at the most popular songs from that time and forward as these will be the songs that most there will have grown up listening to. It is not about the music as much as it is about interacting with them. Get to know them share your life with them as for many you will be there only visitor that day they are just people like you, who have come to hear you play.
