"Ar Hyd y Nos" (English: All Through the Night) is a Welsh song sung to a tune that was first recorded in Edward Jones' Musical and Poetical Relics of the Welsh Bards (1784). The most commonly sung Welsh lyrics were written by John Ceiriog Hughes (1832-1887), and have been translated into several languages, including English (most famously by Harold Boulton (1859–1935)) and Breton. One of the earliest English versions, to different Welsh lyrics by one John Jones, was by Thomas Oliphant in 1862.
