A smooth rumba version of the Norah Jones hit "Dont Know Why" for jazz ensemble in a straight-ahead style suitable for ballroom dancing. Scored for full jazz ensemble with five saxes, four trumpets, four trombones, guitar, piano, bass and drums. Moderate trumpet and trombone ranges make this within reach of most jazz bands--college and pro bands can easily sight-read it. Includes a full score and complete set of parts. Key of Bb.
