If you want to perform in a nursing home, I personally think there are still some revolutionary songs that they will like better, because in nursing homes, many old people come from the war years and are very friendly to revolutionary songs, such as "Without the * * * production party, there would be no new China".
Or start with the songs that the old people like, because then the old people will be more interested. I recommend singing red songs, such as "The East is Red" and "Singing the Motherland", which are familiar to the old people and can better integrate them into their own songs.
