The Arnold Book of Old Songs is a collection of English, Scottish, Irish, Welsh and French folk songs and traditional songs, with new piano accompaniments by Roger Quilter. Quilter dedicated it to and named it after his nephew Arnold Guy Vivian, who perished at the hands of German forces in Italy in 1943. The collection consists of sixteen songs: five songs were written in 1921, and another eleven were written in 1942. Only the latter eleven were written with Vivian in mind at the outset.
