The songs were indeed a treat to the senses and you can easily forget the choir's mischief and misdemeanor at the hotel.  The animation was commendable and clearly conveyed the vivacity and love of adventure of these youth who breaks away from their conductor and experience the thrill of elevator rides, among others.  This may seem as a sign of breaking away from the monotony of endless hours of choir practice.  Well-executed and with choral songs that are uplifting.
