Here are some other songs that could work. I'm currently putting together some Picture Videos for the family and these were suggested to me.

Song of the South by Alabama
I've Been Everywhere by Johnny Cash
Southern Accents by Johnny Cash
Our Town by James Taylor
You've Got A Friend by James Taylor

(these are great for those 'down south' families

Keep Holding On by Avril Lavigne
Tapestry by Carole King
What a Wonderful World by Louis Armstrong
Drift Away by Dobie Gray
Lean on Me by Bill Withers
I Will Remember You by Sarah McLachlan
With A Little Help From My Friends by The Beatles

Hope this helps.
