"Free to Be ...You and Me" has all kinds of nostalgia for me. When I was 8 years old, my group of friends and I did a theatrical rendition of it, so I know the words to all of the songs and memorized the movie.
It also was of my mom's childhood favorites.
A classic book about individuality and equality without being preachy or cliché (i.e. "just be yourself!"), it's thoughtful and often humorous. The book has colorful vintage illustrations, poetry, music, short stories and skits, and offers great morals, not only for how you think of yourself, but how you think of others and the world. It's is great book for children of all ages.
