Just to clear up the confusion: actress/director/writer Gaby Rodgers was married to songwriter Jerry Leiber at the time that Leiber wrote "Jackson" with Billy Edd Wheeler. Leiber & Stoller were given to using pseudonyms when collaborating with third parties, so Leiber used his wife's name for "Jackson." Similarly, "The Reverend Mr. Black" is credited to Billy Edd Wheeler and Jed Peters, "Jed Peters" being a pseudonym for Jerry Leiber & Mike Stoller derived from the first names of their eldest sons, Jed Leiber and Peter Stoller (yours truly.)
