When the casts of The Lion King and Aladdin found themselves stuck in the same airport earlier in 2015, an idea was born. Seeing how much airport travelers loved their impromptu performance, the two casts decided to make it official with a Good Morning America reprise. "Except for the last two months, this was totally unrehearsed," they joked on the show. "Battle" might be a bit of a misnomer for the Mashup-Medley, though, as the two casts are having way too much fun with each other for the performance to be considered any kind of contest.
