There's a moment in Incredibles 2 where Mr Incredible, Elastigirl and Frozone get a blast from the past. To prove he's a fan, Winston Deavor (Bob Odenkirk) sings a few bars of each hero's theme song. It's a fun moment, but it passes, and things move on. However, if you stay for the credits of the film, you can hear the full, produced version of each of those songs. And if you're interested, you can hear them right now!
