The thing is, I don't think I could bring myself to even judge them as an act on their own merit, simply because of how much contempt I have for any reference that film and that song which almost makes John Legend seem underplayed.
I understand the love for Disney, but why not do something unique like dress up as Monsters Inc characters and belt out a version of 'If I didn't have you'... maybe they'd stand out much better as an act if they chose a Disney film that didn't already have 14687656 versions/covers to compare to.
