The Deluxe version of the soundtrack includes songs that didn't make it into the final cut. Writers Bobby Lopez and Kristen Anderson-Lopez and their daughters perform these demos of songs that almost were. Though I'm pleased with the songs that made it in (except for the "Fixer Upper" one), I would love to hear these tracks recorded by the stars of the film. Some of these songs are just adorable. Here's a sampling, and each piece has an introduction from the songwriters:
"We Know Better"
"Life's Too Short" (LOVE THIS)
