This is the original Helen O'Connell version of When the Sun Comes Out, from her 1957 album "Green Eyes", as recorded with the Marion Evans Orchestra. It is a richly textured and lush, bluesy ballad perfectly suited to a female alto voice. The reeds are written AATTB, with no sax doubles. Brass ranges are very playable too, with lead Trumpet up to high C and 2, 3 & 4 called to reach high Bb. Lead Trombone is written to Bb, with 2 & 3 written to A. The vocal key is G throughout the chart. Although the tempo is indicated at 65 b.p.m. the chart works well at tempos up to 80 b.p.m. A fine arrangement, and a slice of American musical history.
