Choral Choir (TTBB) - Level 4 - Digital Download SKU: A0.818163 By Henry Mancini. By Henry Mancini. Arranged by Philip Le Bas. Jazz. Octavo. 2 pages. Philip Le Bas #3541027. Published by Philip Le Bas (A0.818163). An accessible and unashamedly romantic arrangement for male barbershop quartet of Henry Mancini's song Moon River with lyrics by Jonny Mercer. The song was first sung by Audrey Hepburn, but it is remembered especially for Andy Williams' rendition at the start of each of his television shows in the 1960s. This version particularly brings out Mancini's gorgeous harmonies, as the tune is passed from one singer to another.
