With a story as emotional as Dory's, only an equally as emotional theme song would do.
Fans only got surface information about Dory's life in Finding Nemo, but now that Finding Dory is just around the corner, audiences will learn all about Dory's journey and her family. As any Disney-Pixar fan knows, these animated films can be pure tearjerkers, as can their accompanying theme songs. It probably shouldn't come as a surprise, then, that Ellen DeGeneres (Dory) would ask Sia to perform "Unforgettable" for the end credits.
Written by Irving Gordon, "Unforgettable" was made famous by Nat King Cole in the 1950s, but the song won a Grammy in 1992 when Natalie Cole included it as a tribute to her late father on her album of duets. As for why Sia agreed to the song, she explained, "Dory's story makes me teary. When Ellen asked me, I couldn't refuse!"
"Dory's story makes a lot of people teary," Ellen responded on her show.
