Home Movie - Need Some Songs

[Chief911]

Ok. Flame away boys.

I'm making a home movie with film taken while on vacation. I need a fun/good/kids songs for the following types of footage:

1. A ride on a historic train
2. Time at a playground
3. Driving through an outdoor animal park
4. More driving through outdoor park

Examples of songs already being used:

Holiday Road (National Lampoons Vacation)
Old McDonalds Farm
Walkin on Sunshine

Help a creatively stunted person please?
