Composed in 1938 by Joe Garland, a renowned Black saxophonist and arranger, based on an old blues tune. It became a signature tune for the Glenn Miller Orchestra after their recording in 1939.

In Japan, it is popular as a standard jazz piece, having been used in films and TV dramas such as "Setouchi Shonen Yakyu-dan" and "Swing Girls".

The original piece features an exciting intro followed by a theme melody that progresses through call-and-response between saxophone and brass ensembles. While this arrangement is stripped down to just the melody and bass, it is crucial to listen carefully to the original piece and play with clear articulation and dynamic contrast to evoke a big band atmosphere on a single piano, ensuring an overall sense of swing.

It is important to distinguish between notes that should be played with a sinking weight and those that should be played lightly, utilizing an upward lift.

To feel the underlying harmony while playing, practice methods such as "right-hand block chords + left-hand bass" are recommended. You will clearly notice that the theme melody is constructed solely from arpeggiated B♭, E♭, and F chords. When playing this melody, avoid unnecessary wrist movements. It is also beneficial to imagine the interjections of wind instruments, such as a "woop-pah" sound, while playing.
