The Origin of John Coltrane's Spiritual

Like Coltrane's "Song of the Underground Railroad," which was a jazz interpretation of "Follow the Drinking Gourd," Coltrane recorded another song directly based on Negro Spirituals. His "Spiritual," recorded multiple times at live shows in the 1960s provides the listener with a jazz interpretation of an exceedingly rare version of "Nobody Knows The Trouble I've Seen (or Nobody Knows de Trouble I See, according to the original title). This melody is quite distinct from the commonly known version, but more beautiful in my humble opinion.
Look for the sheet music in this google book http://books.google.com/books?id=cP-vouiZ0JsC&pg=PA140&source=gbs_toc_r&cad=4#v=onepage&q&f=false
On page 140 you will see the sheet music. The book itself is a collection of Negro Spirituals with arrangements by James Weldon Johnson and his relative, J. Rosamond Johnson, published in 1925. Apparently Coltrane had a copy of the book or knew of somebody who did, which inspired his "Spiritual."

Unfortunately, I couldn't locate an actual recording of this alternate "Nobody Knows" but I found another song that uses it as the basis for the song. Charles Brown, a blues pianist who was most successful in the 1940s and 1950s recorded it in the 1990s.

Coltrane's recordings of "Spiritual" are epic, especially the 20 minute long version performed at the Village Vanguard in New York with Eric Dolphy on bass clarinet, an instrument rarely used in jazz. Indeed, the reasons I appreciate "Spiritual" so much are due to Tyner's piano playing and Dolphy's bass clarinet solo midway through the song. I believe "Spiritual" is one of Coltrane's most powerful songs, but he should've kept the original title so more people would know of this stunning alternate form of "Nobody Knows the Trouble I've Seen."
