What are your top 5 most requested nursing home songs?

I'm now working with another guy as a duo. Two guitars and 2 vocals. I wanna compare my list to some of yours.

I'm finding as I get older the music is shifting. 10 years ago the old jazz standards were the common fare. Being out there again, I'm finding only the most popular timeless songs from the great american songbook are recognized. It's seems to be trending to the 50's and early 60's with some 70's adult contemporary in there.
