Elastigirl’s Theme from Incredibles 2, music and lyrics by Michael Giacchino. We hear the character Winston sing a bit of it in the movie before Helen cuts him off, but how about some other versions?

Let’s start with a Dcappella, featured on the Incredibles 2 soundtrack;
Up next, Signing Hope gives us an ASL version;
Christopher Bill shows off his skills on the trombone in this instrumental cover;
last we have Michael Brinzer with a little help from his friends all calling in with their parts.
