Joe,
I have a friend who plays at assisted living/nursing homes for a living. Two gigs a day, 5 days a week, 50 weeks of the year.
Here a link to one of his websites:
http://johnboda.com/On the left side, click on the tab that says, Song Lyrics - Chords
This will take you to page that has about a hundred of the songs he uses with lyrics & chords for what he call the Great American Songbook.
Hope that helps.
