Aretha Franklin's cover of Eugene’s "Tree of Life" was an outtake from the 1973 recording session for her album, Hey Now Hey (The Other Side of the Sky). The song was finally released in 2007 on Aretha’s Rare & Unreleased Recordings From The Golden Reign Of The Queen Of Soul.

Touch me feel you change

Locked door lost key

Touch me freak me

Catch the spiral falling upward

God is watching, God is dying”

—“SLOW CHANGE”

Natalie Cole
"Reverend Lee"

Natalie Cole recorded "Reverend Lee" on her 1999 album Snowfall on the Sahara on Elektra. "Reverend Lee" had previously been recorded by Roberta Flack in 1970 release, Chapter Two, and by Eugene (aka The Left Rev. McD) on his 1971 album, Outlaw. About the song, one reviewer posits whether it might not be autobiographical: “Reverend Lee” is an undeniably excellent bit of country funk that tells the story of a tryst with Satan’s daughter, ending in what might be termed a “pitchfork wedding”; keeping in mind McDaniels’s adopted alias, one can’t help but wonder if there’s a bit of truth to the story.” —Scott Hreha, Popmatters.com http://www.popmatters.com/review/mcdanielseugene-outlaw/
