songs for an anniversary party?

[Coco]

Hi
I was wondering if anyone would be able to suggest some song titles for an 25th wedding anniversary party.
My daughter's been asked to sing a few songs at her friends parents do in the spring. They have a swing band and they have asked for' Sway' and a couple of similar upbeat swing songs. ? Also some cheerful pop type songs which they want her to perform to backing tracks.
She sings classical stuff usually ,but when she sings pop , her voice lends itself to the Leona Lewis type of music.
Any suggestions for suitable songs would be greatly appreciated !!!
Thank you !!

How about - Honey honey - Abba
Son of a preacher man
Mercy - Duffy
Sweet about me - Gabriella cilmi
Venus - Bananarama
I will survive - Gloria Gaynor
Lady Marmalade

Don't know whether it helps, but when I organised a surprise party for my parents' 40th, I researched all the songs that were number one during the year that they got married, and concentrated on those (if you could find someone who was at the wedding and remembers what their "first dance" song was, all the better!!)

I'll bet there are a few songs that would suit your daughter's voice amongst that lot...
