Well brink,as you know the original was from his 1968 LP,"Back Here On Earth". He re-made the song during 1977 recording sessions for "Endless Wire". I believe he changed it (if I recall the liner notes of "Songbook" correctly) because he was not all that excited about the original. If any lyrics were changed later either he just wanted them to sound more up to date or maybe the line about his name being mentioned sounds a bit self-centered. Sometime ago,Gordon realized a few of the songs he had done early in his career were quite male chauvenistic. You know.."I'm the man so I'm better and stronger than the woman" kind of songs. Back then the music world was filled with male singers who wrote songs that way. Yuck! It's been Borderstone,outta here and Alberta Bound!
