The Broadway casts of "The Lion King" and "Aladdin" hosted an impromptu a cappella sing-off at LaGuardia Airport after storms delayed numerous flights Sunday night.

The casts were stuck in the airport for six hours after their flight to Orlando was delayed on Monday, according to Mashable. The casts of each musical took advantage of the downtime with a sing-off, captured on video by bystanders.

"The Lion King" cast started off with its opening number, "Circle of Life." The "Aladdin" cast then fought back with a freestyle rap by James Inglehart, who plays the Genie character.
