The Swingle Singers often use "Flight Of The Bumble-Bee"as an encore piece. It has to go as fast as possible using a great variety of scat syllables in order to avoid lock-jaw. It also includes a fairly literal vocal transcription of Debussy's famous piano piece, "Claire de Lune." The tessituras are quite wide ranging from low D-flats for the basses to high B-flats for the sopranos. It is probably best sung with the help of microphones. This transciption of a Chopin "Etude Op. 25 No.9" is probably easier to sing than it is to play! It should be performed at a brisk pace, with the main melody alternating between the Tenors and the First Sopranos.
