The Simon Sisters (Lucy and Carly) had three albums on Kapp and one on Columbia (reissued later with additional background) with many poem songs. The Coumbia one included Who Has Seen the Wind, The Lobster Quadrille (Lewis Carroll), The Lamb (Blake), Wynken, Blynken and Nod, and I Heard the Bells on Christmas Day. A wikipedia article with their discography is http://en.wikipedia.org/wiki/The_Simon_Sisters.

Also, much or all of Blake's Songs of Innocence and Experience has been set by William Bolcom, and also by Hampton, VA's Mike Hassell.
