This was more like when I was in sixth grade, but in Girl Scouts we had lots of fun songs that we sang. One of them was a more interesting version of Mary had a Little Lamb. i don't remember all of the verses, but here are a few
Mary had a little lamb, it's fleece was white as snow
Shoutin' out the battle cry of freedom
It followed her to school one day, which was against the rules
Shoutin' out the battle cry of freedom
(Chorus)
Harrah for the Mary
Harrah for the lamb
Harrah for the teacher
Who didn't give a pot of gold if all the lambs in Idaho came marching off to school
Shoutin' out the battle cry of freedom
When Mary had a little lamb, the doctor was surprised
Shoutin' out the battle cry of freedom
But when old McDonald had a farm, the doctor nearly died
Shoutin' out the battle cry of freedom
Chorus
I eat my peas with honey, I've done it all my life
Shoutin' out the battle cry of freedom
It makes the peas taste funny, but it keeps them on my knife
Shoutin' out the battle cry of freedom
I know we had a lot of fun songs that we sang all the time, but I really can't remember them!
