I am looking for songs to use in a slideshow for a cheerleading squad with girls ages 6 and 7.?

we are putting a slideshow together for the end of season banquet and are in need of songs about friendship, saying goodbye, or remembering one another. I googled and can not find anything good, so I am looking for suggestions. This is their first year cheering and they will all be split up and sent to different squads next year, so it is meant to be a keepsake for the girls and parents. We already have picked out " I will remember you" by Ryan Cabrera, but we still need three more songs. Any suggestions??
