I am making a picture video of memories for my nursing class as well. So far I have used the following:
Whenever you remember by Carrie Underwood
Time of my life by David Cook
Do I make you Proud by Taylor hicks.
With the last song I decided to use our individual pictures from pinning as the last of the song then end with a group picture.
I am looking for more though because we have all taken a ton of pictures. I thought about adding I will remember you by Sara Mcclothlin. (I think thats how you spell her last name )
Let me know if this helps.
