I usually include some show songs, "Some enchanted evening", from South Pacific
Getting to know you, and shall we dance? from King and I,
All the things you are
When you wish upon a star
Forgotten Dreams (Leroy Anderson)
Sunrise, sunset from Fiddler on the roof
Somewhere over the rainbow
Some ragtime waltzes such as Augustan Club (Joplin)
Depending on the context, some light classics, Elgar's Chanson De Matin, the polotsvian Dances, Pathetique Sonata, etc.
Also Summertime, I got rhythm, theme from Rhapsody in blue as a piano reduction,
I also group them by either style or key, and segue five or six together. It takes some planning, and also I sometimes use reduced scores so I can put 2 or 3 on the stand at a time.
What is the event?
Anniversary waltz . . . . .
