The text of "In Evil Long I Took Delight" is in the Cyberhymnal, with a midi of its well-known tune (not "Amazing Grace"): In Evil Long
Music is attributed to Hugh Wilson (1800), and arrangement to Ralph E. Hudson, ca. 1885. Hugh Wilson was a Scot (1766-1824), Hudson (1843-1901) was from Ohio (wrote several religious songsters).

Newton is listed as composer on some 288 tunes in the Cyberhymnal (the Olney hymns) list, but only a few of these are given in complete form in the hymnal.
