This version of 'I Guess I'll Have To Change My Plan' was recorded by the great Tony Bennett with the Count Basie Orchestra and is a laid back swinger in true Basie style. Our only change to the Ralph Sharon original is to voice the brass for an 8 piece section. Aside from the big instrumental soli in the middle of the chart it is the saxes who do most of the backing lines behind the vocal, using some innovaive voicings to give the chart a great jazz feel. The Trumpet lines are quite high, with lead reaching high F# and second to high C#. Although not a long chart, it is a classic of its genre, and worth its place in any library. Another great transcription from Jon Harpin. The vocal key is C and there are no sax doubles.
