Bill, of course a lot depends on the venue/audience, but if you look for songs by Brooks and Dunn, Brad Paisley, Blake Shelton, I'm sure you will find some nice stuff ...

At a restaurant gig I've played songs like:
Blue Neon
We Danced
Neon Moon
The Dance
If Tomorrow Never Comes
Feels So Right

I'm sure others here can help, and DonM could give you an encyclopedia ...
