Dave Wolpe's superb chart on this great jazz standard is for vocalist and jazz ensemble and it is arranged in two keys for flexibility. The low key is C and the high key is F...just flip the page for the preferred key!  In addition, an optional part is provided for tenor sax as an alternative to the vocal.  A terrific stop-time sax soli and a jazz solo for 2nd trumpet are more highlights of this swinger. The low key vocal range is Gb below middle C to second space A.  The high key range is B below middle C to fourth line D treble clef.  A great vocal feature that swings all the way home!
