The original Ella Fitzgerald chart was scored for a big band, augmented with a lot of orchestral woodwind. Jon Harpin has skillfully adapted the original concept to make the chart playable by a regular 5444 big band line-up without losing the flavour and feel of the original. The chart remains a beautiful, even tempo vocal ballad full of tonal colour and harmonic richness. The vocal key is G throughout and there are no sax doubles.
